Subject: Anova, F statistics, P-values
In-Reply-To: <web-426420671@cgpsrv2.cis.mcmaster.ca>
Thank you for the replies.
I am actually trying to gain p-values and f values, and tried the below
script but unsuccessful.
1) I have read in another forum to use the package lmer but apparently it
does not exist.
2) Then I tried the pvals.fnc but it is not a function.
3) I read also that a glm model must first be created but was not able to
gain a P-value through summary but got F statistics.
4) Is there a way to get the P-value and F statistics? Or does this require
two different executions?
5) I am afraid to update my R version because I may loose my ALL saved
scripts, should I do so?
Please advise, Jean
