Hi,
I am looking at the effect of allelochemicals produced by two freshwater
macrophyte species on two different algal species at different days. I am
comparing the effect of each macrophyte on each algae at each day. I received
help from someone doing the LMEM (Linear mixed-effect models) and he told me to
do ANOVA to analyse the LMEM. However, I received these feedback from my
examinor;
1. An Analysis of Variance (ANOVA) was used to analyse the LMEM.
Comment; Not clear why you used ANOVA here. Was it to compare models?
2.The effects of TREATMENT and TIME and their interaction were all significant
(Table 5). Because of the significant interaction, the analysis was split by
TIME.
Comment; Given that you have interactions, you should do a model selection to
show whether the interaction model is in fact more parsimonious.
Can someone explain these and tell me how and when should I do model selection?
Thanks,
F
