Re: Is there any way to convert Complex Survey data into regular data?

Thank you for your reply! To answer your question, the regular ML method I meant decision tree or random forest kind of things. I know it's not necessary to use weights for these tree-based methods as they don't use estimated variance but just curious about if there's any way to incorporate weights so that the results are more representative. And the simplest way I could think of was to convert a weighted dataset to a regular one but looks like it's not realistic. ... View more

Thank you for your response. And let me clarify my goal.    I need to use complex survey weights (e.g., strata, cluster, weight) in my analysis so as to avoid bias. However, a lot of machine learning functions do not support complex survey design, so I am looking for a way to convert the complex survey dataset into a regular dataset according to the complex survey design (i.e., weights). In this case, we could directly use regular methods but just input the converted dataset for further analysis. Did I make sense?   Look forward to further help. Thanks! ... View more

I am trying to do an analysis on a Complex Survey dataset. I am wondering if there is any way to convert a Complex Survey dataset to a regular dataset by the survey weights and re-sampling or other techniques. I’ve searched around and only found that the SURVEYSELECT procedure might be related but it doesn’t work exactly. For example a complex survey dataset with sample size 10000 might become sample size 100000000 after conversion; however, the SURVEYSELECT proc has a cap of sample size equals the original sample size, i.e., 10000. To sum up, I just wanted to find a way to convert a Complex Survey dataset to a regular dataset. Look forward to any suggestions or help! ... View more
