Abstract: nscale provides a convenient way to recode variables to lie between 0 and 1 via dividing var-min(var) by max(var)-min(var). nscale can recode many variables at once and has options gen() and pre() which work in the similar manner as Stata’s default command recode does. It is also possible to store transformed values in existing variables with option nopost. nscale can set specific value or interval to missing (.) as well. For example, if a survey question q1 coded DK as 98 and miscellaneous as 99 and you want to exclude those values from analysis, just type: nscale q1 , m(98) up. Then nscale sets all observations whose value is greater than or equal to 98 to missing (.). The option down combined with option m(#) works similarly. Moreover, nscale does reverse coding with option r and tabulates new variables with option t.
