Ancova: formula with a common intercept
...s share the same intercept. How do I define this? I
tried this:
> ancova2<-update(ancova,~.-1)
> summary(ancova2)
Call:
lm(formula = Result ~ Time + p53 + Time:p53 - 1)
..
Coefficients:
Estimate Std. Error t value Pr(>|t|)
Time -0.02134 0.01785 -1.195 0.241
p53minus 0.05919 0.55646 0.106 0.916
p53plus 0.22977 0.55646 0.413 0.682
Time:p53plus 0.11887 0.02524 4.709 4.62e-05 ***
But I do not think that is doing what I want.
Many thanks
