Hello,
I would like to perform a multivariate regression analysis to model the
relationship between m responses Y1, ... Ym and a single set of predictor
variables X1, ..., Xr. Each response is assumed to follow its own
regression model, and the error terms in each model can be correlated.
Based
Dear Ernest,
The ML estimator for the mulitvariate linear model assuming multinormal errors
is the same as equation-by-equation LS, but multivariate tests performed for
all of the responses on the resulting multivariate linear model object (e.g.,
by anova() or Anova() in the car package) will

My doubt is how to access plot identities after the tree is produced.
For us it is rather important,

the systemfit package can do that and the documentation is quite nice
also

Hi all,
I'd like to fit a multivariate regression with the variance of the error term
porportional to the predictors, like the WLS in the univariate case.
y_1~x_1+x_2
y_2~x_1+x_2
var(y_1)=x_1*sigma_1^2
var(y_2)=x_2*sigma_2^2
cov(y_1,y_2)=sqrt(x_1*x_2)*sigma_12^2
How can I specify
