[R] standard errors

[Bill.Venables at csiro.au]

vcov(my_fit) should get you the whole variance matrix, so
sqrt(diag(vcov(my_fit))) should get you ONLY the standard errors.

Subject: [R] standard errors


Hi, guess my problem has simple solution. 
I want to extract ONLY Std. Errors of Max. Lik. estimates
(my_fit<-mle(object,...)), the same as I can do with estimates by:
x<-as. matrix(coef(my_fit)).
I could not find any function similar to 'coef(my_fit)', which extracts
only
Standard Errors. So far all I can do is to type: summary(my_fit) and
then
get the whole output (with Standard Eroros involved).

thank you in advance and best wishes, robert
