By WLS we mean weighted least squares regression. On page 111 in Brewer, KRW (2002), Combined survey sampling inference: Weighing Basu's elephants, Arnold: London and Oxford University Press, he...

From what I have read, OLS regression is the core of more complex modeling, such as used for panel data, with which I am not so familiar. Even in 'one-level' modeling, say the often used case of...

Much work by W G Cochran might apply, and by Sir Ronald Fisher, as well as other historical developments, such as the Youden Square. I'm partial to work by Ken Brewer which applies with regard to...

Are omitted variables a subset of lurking variables, where the word "omitted" is only used when bias is the focus? Or perhaps there is some other matter of context? I find I am not clear on the...

Fellow RGers: A recent survey statistics and methodology journal had an article on the use of splines, and as one example they used data with which I am very familiar. In that case, however, I...

This, to me, is a huge mistake, as a cross sectional survey is designed to estimate what is currently happening. A time series forecast for that period can incorporate seasonality, but not a new...

My experience with regression is primarily with regression through the origin, not necessarily with one regressor, but let us consider that. This is generally the case when examining establishment...

I have searched for such establishment survey data so that I can try applying methodology to them for which I previously led development on official energy statistics. The idea is to impute...
