The viedo is very good, it crealry explain a important statistical method. I am novice to R and I would say that a lesson that takes 3 or more package to be installed tells us that probably R is not for everyone: every package has its logic, its syntax, and so on, for example when a version change sometimes the syntax is non loger valid, that is probably the case with the error we take in using cld function.

I come to your page repeatedly for you actually a great job here. Thanks!!!

Life saver !!! Much love.

This is GREAT! Thank you.

Thanks a lot! very clear. But I have a question, I compared the 2-way ANOVA results in SPSS and R, but they are different, could you tell me the possible reason? thank you

Hi. Why do you use lsmeans instead of tukey.hsd? Thank you.

HI, I have watch the two anova video. in the first video, the p value of predator_debsity:timing is less than 0.5, so you delete the factor predator_debsity:timing in the second the video. could you explain the reason?

Hi, my dependent variable is the number of questions answered in a privacy sensitive context (0-19). Can I also use the ANOVA for this count data ?

As for the error we take using cld function: 1) install package multcomp: install.packages("multcomp") 2) load the library multcomp: library("multcomp") 3) change the syntax of the cld function: cld(posthoc[[1]], alpha=.05, Letters=letters). Hope it works for you.

If either the Levene's test or the Shapiro Wilk test were not > 0.05, would you not be able to run the two way anova? Is there a non parametric test that could be used?

Hi I am having this problem, can you help me to solve this Error in UseMethod("cld") : no applicable method for 'cld' applied to an object of class "c('emm_list', 'list')"

Hey! does anyone know the solution to the following error message? Error in UseMethod("cld") : no applicable method for 'cld' applied to an object of class "c('emm_list', 'list')"
