Dear List,
I am running S-Plus 2000, professional release, and I am looking for the
function to compute the adjusted R2 (adjr2 as in R) on a linear model.
I only get the unadjusted R-squared when running the command as below.
I would appreciate it if anyone could share their experience.
Thanks very much in advance
Julia
test1<-
lm(data=landscape,AREA.MN..change~+AREA.MN.initial+FinalSeismic.Densitymperha+FinalSeismic.Densitymperha^2)
> summary(test1)
Call: lm(formula = AREA.MN..change ~ + AREA.MN.initial +
FinalSeismic.Densitymperha + FinalSeismic.Densitymperha^2, data =
landscapelevelmetricchanges.paperversion.bothlines)
Residuals:

Residual standard error: 4.491 on 100 degrees of freedom
Multiple R-Squared: 0.8386
F-statistic: 173.3 on 3 and 100 degrees of freedom, the p-value is 0
