Get Statistics results in a program...

[salvomic]

hi,
why I get error with this code?

Code:


myvar:= Statistic_2var.MeanY;

but not with

Code:


myvar:= Statistic_2var.Resid();
// or myvar:= Resid();

?
if I type "Statistic_2var.MeanY" in CAS or Home it's ok, but I get error in a program...
where I'm wrong?

thank you in advance,
Salvo
