Dear Steven,

CALC ; newe= xbar(3)
     ; newe= newe^2/10  $

MATRIX ; xbar(4,*)= newe $


should work.

Best Regards,
Harald

Betreff: [Limdep Nlogit List] Help with basic matrix command

Can somebody help me change an element of a vector? In the following, vector xbar is 4 x 1.
How can I replace the last (4th) element with "the square of the 3rd element divided by 10". Thank you!

sample ;1-30 $

create ;x1=rnp(1.2)+1 ;x2=rnp(2.1)+1 ;x3=rnp(3)+1 ;x4=x3^2/10 $

name ;x=x1,x2,x3,x4 $

matrix ;list ;xbar=mean(x) $
