<ul></ul><p>Peter,</p>
<p>Thank you for your question. Indeed, stratification used in the design was very detailed in order to improve precision. This does result in the issues you describe. There are a few alternatives for you:<br />1. ignore stratification. This will not introduce bias (stratification influences only standard errors), and will make your estimates more conservative - confidence interval will be higher than it is by design.<br />2. You can create strata variable yourself such that there are at least 2 clusters per strata. Note, that because strata variable has ordered values, you can combine the adjacent values.</p>
