Dear Statalisters,

I wrote the following simple ado file.

/*----------myboxcox.ado----------*/
program define myboxcox
version 7
local y = exp(`1')
if `y' == 1 {
   di in gr "f = " 1
   }
else {
   local f = (`y' - 1)/ln(`1')
The log of 1 is zero, so you are doing division by 0. Did you perhaps mean ln(`y') instead?
