Abstract: This command standardizes test scores with respect to the mean across age (a running variable) assuming normal distributions given age. Additional variables can be specified over which the test variable is age-standardized. For example, a test score could be standardized over age and sex. Additionally, a subpopulation can serve as a reference population for standardizing the scores of other observations in the same dataset. Continuous and discrete options are available, as well as Tobit adjustments for ceiling and flooring effects. The program creates a new z-score variable, stx_testvar, and provides diagnostic graphs (grc1leg must be installed for the graph option).
