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.
