Help on parameters
Hi,
I have a follow analysis
Trat1 = quantitative variable
Trat2 = qualitative variable with 3 levels (A, B, C)
Trat3 = qualitative variable with 3 levels (D, E, F)
Resp = Response
I try to get the parameters to compare with zero, so I make this model:
glm(Resp~Trat1*Trat2+Trat1*Trat3-Trat1-1)
The -Trat1 is to make comparison of slope with zero.
The -1 is to...

multiple comparisons in nested design
...tercept):List of 9
$ patient :List of 9
$ Within :List of 6
#> AnovaModel.3<-AnovaModel.2$patient
#> attr(AnovaModel.3,"class")
[1] "aov" "lm"
This model is suitable for confidence intervals:
#> confint(AnovaModel.3)
2.5 % 97.5 %
trat2 -0.9107959 0.5462655
trat3 -0.9848351 0.4722263
trat4 -1.2997235 0.1573379
trat5 -1.0623118 0.3947496
But it is useless for multiple comparisons:
