WebHowever, researchers rarely explain which estimate of two-way clustered standard errors they use, though they may all call their standard errors “two-way clustered standard errors”. My note explains the finite sample adjustment provided in SAS and STATA and discussed several common mistakes a user can easily make. and Webtheir approximate standard errors by using the delta method. SAS PROC NLMIXED enables the user to specify a conditional distribution for the data (given the random effects) having either a standard form (normal, binomial, Poisson) or a general distribution that the user can code using SAS programming statements. The latter feature makes
