Re: st: Re: rescaling variables
Dear Kit,
Thanks so very much! Initially I thought to replace the
missing values by zero as well, but then confused myself
by thinking that a zero value (the smallest value for the
x-variable) should translate close to -1.96 and beyond for
the z- variable. Thanks again!!!
Suryadipta.

If there is no variance for a particular country, the
deviations from means are all zero, so
a standardized value of zero is appropriate.
