			<description><![CDATA[I’m trying to decide on a robust method to handle missing values in a longitudinal survey dataset I’m analyzing, and I’m stuck on whether multiple imputation is the right approach for my case. My concern is that the missingness seems to be monotone for a key variable but intermittent for others, and I’m not fully confident my model assumptions are correct for the imputation process.]]></description>

The variance is about 1.8 times the mean, so it’s overdispersed, but I’m not sure if that’s enough to justify the added complexity of the negative binomial’s extra parameter.]]></description>

My point estimate suggests a positive lift, but that interval makes me question if the effect is real or just noise. How do you decide whether to call this a win or not?]]></description>
