Dear Anatoly,
We have a function (linear_regression) for multivariate linear
regression. Here is an example:
http://riotorto.users.sf.net/statistics/multivariate_linear_regression.html
The function returns the m.l. estimates of the parameters, confidence
intervals, p-values for testing null hypotheses H0: beta_i=0, residuals,
Akaike's information criterion (AIC), and some other things.
We don't have a function for showing the analysis of variance table
(ANOVA), but the main information is returned by linear_regression.
Some non?inear models could be fitted with an appropriate
transformation, or adding new columns to the input matrix, as in
polynomial regression, for higher degree terms.
For documentation, type
? linear_regression
Not sure if this is what you need.
