<p>Dear Stephanie, <br />the handout to the question about matching info of any two hh members states that I quote: "In this example we will be using data from Wave 1, but the method will work with data from any wave."</p>
<p>Question: Does the method also apply to an analysis across waves including all waves?</p>
<p>The reason I ask this is because if I look at my wage regression I have an estimation sample for married women with roughly 28,000 married females (given the control variables). When I follow the method described in the handout (example 7) and use the same control variables, I only have roughly 19,000 married (matched) females in my wage regression. I seemed to have lost quite a number of observations through the matching process.</p>
<p>Thanks.</p>

<p>Dear Alita,</p>
<p>I would like to have some labor market outcome information of children whose parents participated in the survey. I want this because I would like to have both labor market outcomes of parents and their children. For instance the wage of children and the wage of their associated father or mother. Not sure if this is feasible.</p>
<p>Any suggestions from you are as usual very much appreciated.</p>
<p>Best wishes.</p>

<p>Hello Alita,</p>
<p>hope you are fine. I do have a question with regard to merging the above files. It is my understanding that in the districts (6666) data set I have household number and the variable for district in each wave file (in addition I generate the wave variable for a through g). I am not sure how to proceed. Do I produce and append all seven waves for the district data set first and then merge it with the main data set or do I merge each district data set (of each wave) individually with my main data set? If I appended all seven waves of the district data set first, I would suggest doing the following:</p>
<p>merge m:1 hidp wave using districts_appended_a-g</p>
<p>Now the thing that is not clear to me is that if I have two people with two different pidp's living in the same household (hence sharing the same hidp) in a given wave, how can they be uniquely identified in the using data set?</p>
<p>Once again, I would highly appreciate your suggestions.</p>
<p>Best wishes.</p>

<p>Hello user support,</p>
<p>I am hoping to get data on cognition for the subsample introduced in wave 6 (IEMB). For that purpose, I am wondering if the planned cognition testing for wave 9 will be taking place and if it will cover the IEMB as well.</p>

<p>Hi Alita,</p>
<p>this is my last question for you for a while, promised. I would like to get your general take on it though. It somewhat relates to my other open issue which you are working on.<br />I would like to have the number of all children born by a given female respondent (my open issue for which you are currently checking my suggestion) and in addition their birthyear.<br />I found this: <br /><16 in household: w_birthy from w_child <br />out of household: a_lchdoby, f_lchdoby (year of birth of non-resident biological child) from w_natchild <br />Now I would like to generate a variable call it birthyear_1_dv for first kid for all female respondents for all seven waves with birthyear_1_dv = 0 if the women is childless. <br />And then birthyear_2_dv for the second kid for all female respondents etc. or something like that. <br />If you happen to have some general suggestions as to how to go about generating such variables, I would highly appreciate your input.</p>
<p>Best wishes and thank you very much.</p>

<p>Dear Support Team,</p>
<p>I am looking for the total number of siblings of a given respondent (gender is irrelevant).</p>
<p>I could not find it, and I am not sure if there is information available to derive such a variable.</p>
<p>Your help is much appreciated.</p>
<p>Best wishes.</p>

<p>Dear Peter, <br />I have a quick follow-up question with regard to my past issue <a class="issue tracker-3 status-5 priority-4 priority-default closed" title="Support: Pooling data from all waves, 1-6, using all subsamples of USoc (GPS, EMBS, BHPS, IEMB) (Closed)" href="https://iserredex.essex.ac.uk/support/issues/839">#839</a>. You wrote the following below:<br />A simpler approach would be to select based on current wave GOR. This will not remove the sample imbalance problem, but should reduce it to a minimum, so may be good enough.<br />For me to implement this simpler approach and to minimize the sample imbalance, you suggest to drop Scot, Wales, NI for the current wave g only? Or do you mean to drop all Scot, Wales, NI for all seven waves? <br />I would appreciate a short reply and sorry about the very delayed follow-up question. <br />Best. <br />Nico</p> Understanding Society User Support - Support #917 (Resolved): how to merge xwavedat with data fro...https://iserredex.essex.ac.uk/support/issues/9172018-02-12T10:05:40ZNico Ochmannnico.ochmann@postgrad.manchester.ac.uk
<p>Dear Alita,</p>
<p>this seems an obvious procedure, but I obtain a fairly high number of non-matches (60,792), which kind of concerns me. <br />This is what I do and I cannot detect an obvious mistake. <br />Your suggestions are highly appreciated, as usual. <br />Best.

<p>Dear support-team,</p>
<p>I am wondering about the qfhigh_dv variable and immigrants who got their degree outside the UK. It seems to me that there is no problems with immigrants who got their degree in the UK. However, immigrants who hold a foreign degree might not find the equivalent in the questionnaire for the qfhigh_dv variable and simply report 'none of the above' (96). In my estimation sample, immigrants who got a foreign degree are well distributed across all of the listed degrees in the questionnaire. I use qualoc and imputation methods to infer the location of the degree. My question to you is if I should be concerned about the '96' entries for immigrants. It seems to me that as long as the entries are not systematically towards highly educated or low-educated or any other group, I should be fine. I realize that this question might go beyond the purpose of this forum, but if it does not, I would appreciate a reply.</p> Understanding Society User Support - Support #879 (Closed): macob_all and pacob_all in xwavedat_p...https://iserredex.essex.ac.uk/support/issues/8792017-11-12T14:54:20ZNico Ochmannnico.ochmann@postgrad.manchester.ac.uk
<p>Dear Alita,</p>
<p>I hope you are doing well. I have noticed that macob_all and pacob_all are not available in xwavedat_protect, but just macob and pacob. I am wondering why this is the case. I did notice that they are present for each individual wave in the special licence version. <br />Will you guys make these variables available in wave 7 for the protected dataset? <br />If not, what would be an elegant way to construct these two variables from the individual waves.</p>
<p>Thanks a lot for your help once again.</p>

<p>Dear Alita,</p>
<p>if I understand the variable description correctly, englang is unfortunately not part of xwavedat. Whether English is first language is asked both immigrants and natives in wave one, and the IEMB in wave 6. <br />For wave 5, the englang variable appears as well. I want to use all six waves in USoc, for the years 2009-2015. For that purpose, I need to impute the information I have on englang to the missing waves/years. <br />So far, I have used the information from all three waves and generated a new variable englang_dv which I then merged m:1 pidp with the rest of the data set. <br />In broad terms, am I doing this correctly? <br />Thanks a lot! <br />Best wishes.</p>

<p>Dear Peter,</p>
<p>sorry to bother you again, but we had that exchange in support <a class="issue tracker-3 status-5 priority-4 priority-default closed" title="Support: weights for pooled cross-sections over waves (a)-(f) (Closed)" href="https://iserredex.essex.ac.uk/support/issues/758">#758</a>. <br />I have been implementing your suggestions as we discussed. I am contacting you now again because I would really appreciate you <br />having a quick look again at our previous exchange and this current issue. With the weighting scheme, my results change quite a bit (point estimates and standard errors), so I really want to make sure that I am doing things right. I do think I do, but I rather double check. <br />So I am using all subsamples of all six waves and I generate a new weighting variable accordingly (newwgt). I use these observations across waves as if they were repeated cross sections. For various reasons, I cannot utilize the panel data structure. The time dimension of the pooled cross sections is not the wave variable, but the year variable, istrtdaty, start of the individual interview. Given this information and the discussion we had in support <a class="issue tracker-3 status-5 priority-4 priority-default closed" title="Support: weights for pooled cross-sections over waves (a)-(f) (Closed)" href="https://iserredex.essex.ac.uk/support/issues/758">#758</a>, I would highly appreciate your verification of me doing things correctly. <br />Thank you very much in advance! <br />Nico</p> Understanding Society User Support - Support #829 (Closed): What is the difference between qualoc...https://iserredex.essex.ac.uk/support/issues/8292017-08-03T17:46:13ZNico Ochmannnico.ochmann@postgrad.manchester.ac.uk
<p>Dear Alita,</p>
<p>I have been using the qualoc variable for the different waves. However, I am curious about the derived variable. When I check on qualoc_dv, I get more people receiving a degree abroad than in the UK. <br />When using qualoc from the different waves, I get what I expect, large number of folks obtained their degree in the UK. So what is qualoc_dv all about?</p>
<p>I appreciate your insights.</p>
<p>Thanks.</p>

<p>Dear Ladies and Gentlemen,</p>
<p>I am trying to find the gender of the children in a given household.</p>
<p>The children should ideally be under 16 years of age and be the biological kids of the father. I understand that the fertility history variable in the indrep data file gives me the info on the biological father. I am not sure where to look for the gender of all the kids though, if it is available at all. I checked in the _child file where there is a _sex info. Would that be it?</p>
<p>I would appreciate your help.</p>
<p>Thanks a lot in advance.</p>

<p>Dear Ladies and Gentlemen, first of all thank you very much for dealing with my inquiry. My question concerns qualoc variable and the high number of <del>8 associated with it. What does -8 imply in this context? Please look at my following examples. <br />tab qualoc if year==2010<br />uk or non-uk |<br />qualificatio |<br /> n | Freq. Percent Cum.<br />------------</del><ins>-----------------------------------<br />inapplicable | 45,905 83.56 83.56<br /> yes | 7,529 13.71 97.27<br /> no | 1,502 2.73 100.00<br />-------------</ins>-----------------------------------<br /> Total | 54,936 100.00</p>
<p>. tab qualoc if year==2011</p>
<p>uk or non-uk |<br />qualificatio |<br /> n | Freq. Percent Cum.<br />-------------+-----------------------------------<br />inapplicable | 50,294 95.08 95.08<br /> yes | 2,132 4.03 99.11<br /> no | 472 0.89 100.00<br />-------------+-----------------------------------<br /> Total | 52,898 100.00</p>
<p>since I have a panel data set, I do not see how and why the the number of -8 can increase from one year to the other. could it be that you only report those people you got a higher degree degree once and then as non applicable (-8) when they are asked again. I have not clue but those numbers in the above table (when all five waves are pooled) do not make sense to me. Thanks a lot. Nico</p>
