Re: st: How to attach a string to a numeric variable as its value lable |

Xiangping Jia, When you -encode- a string variable, the new numeric variable has the values 1, 2, 3, and so on. These values are probably not the same as those in the variable y. In the example in your message, the label "RAKAI" is assigned to the value 1 and not the value 21 when you -replace newx=y-. Below is an inefficient solution that creates correct value labels. The solution is inefficient because it loops over all observations. . count . local n = r(N) . forvalues i = 1/`n' { local xi = x[`i'] local yi = y[`i'] lab def ylab `yi' "`xi'", modify } . lab val y ylab . lab list ylab ylab: 21 RAKAI 22 MASAKA 23 MBALE 24 SIRONKO 25 TORORO 26 BUSIA Friedrich On Tue, Mar 25, 2008 at 4:32 PM, Jia Xiangping <jiajoseph@googlemail.com> wrote: > Dear all, > > There are two variables, one string and one numeric.
