Re: [R] mixed-effects model with two fixed effects: interaction

IIona- I think you may be misinterpreting the t-test. In model 1, consider the speciesH coefficient. A test that speciesH = 0, essentially asks: Is speciesH the same as speciesB? The test statistic for this hypothesis is the t-value reported in the table. (t-value= -4.2, p-value=0.0001) In mo

[R] mixed-effects model with two fixed effects: interaction

Dear all, In a greenhouse experiment we tested performance of 4 different species (B,H,P,R) under 3 different water levels in 10 replications. As response variable e.g. the number of emerging sprouts were measured on three dates. A simple Anova considering every measurement date separately shows
