Dear community,
Thanks for regr2.plot. I've another question.
When fixing OLS I used training data and test data.
I'd like to know if it's possible to draw the plane I've fixed with the
training data, and draw the observed and predicted points achieved with the
test data. If so any help or
Hi, thanks, I think I've changed the previous as you told me but I'm having
this error, what does it mean?
model- lm(log(v1)~log(v2)+v3, data=dat)
newax- expand.grid(
v2 = seq(min(log(dat$v2)), max(log(dat$v2)), length=100),
v3= seq(min(dat$v3), max(dat$v3), length=100))
fit -

Dear community,
As it's explained I've tried the following:
model- lm(log(v1)~log(v2)+v3, data=dat)
newax- expand.grid(
v2 = seq(min(log(dat$v2)), max(log(dat$v2)), length=100),
v3= seq(min(dat$v3), max(dat$v3), length=100)
)
fit - predict(model,newax)

Hello Masters,
wishing you all a great 2011 I was also going to ask if anyone knows a quick
and efficient way to plot a regression plane (z~x*y).
I have tried the regr2.plot{HH} function but it is only an educational tool
and has poor graphical properties.
I also tried to run the following

There are many. There are limitations to using the ?? operator in that
