Hello,
Is the "std.dev" component of ls.diag( lsfit(x,y) ) the sample standard
deviation of the residuals of the fit?
I have
ls.diag(lsfit(xx,yy))$std.dev
different from
sd(lsfit(xx,yy)$residuals)
where xx and yy are vectors of 5 elements.
Compare
ls.diag(lsfit(xx,yy))$std.dev
with
sd(resid(lsfit(xx,yy)))*sqrt(4/3)
and think about degrees of freedom.
