R help - Nov 2012 - Likelihood ratio

Hi All


I have to run multiple  stimations and to compute Likelihhod ratio.

If I compute ls function with coef and summary I can extract "outputs"
that
I need.

I am not able to find something similar to log liklihood....

Can you pease tell me running a ls function x on y how to extract if
posible LR statitic or Likelihood or Log likelihood.

Many thanks in advance. If you send me some manual or webpage guide I will
be very happy.

I will try to improve my posts and questions.

Do you mean "lm"?

You can use glm' with family="gaussian". Deviance is -2*LL

Of you can look at the code and  see how it does it.
