Manova() function is part of "car" package and not "MASS" package. Telling this to save someones time if they are running on errors with trying to only work with their own data like me.
When the Manova-function in 'Car' is used with type-III SS, the order of the predictors (Depth + Contour vs Contour + Depth) does make a difference when intercept is removed by '-1'. How if intercept is left in the model then the order of appearance doesn't interfere with the model estimation.
Thank you very much for this tutorial. I still have a question: how can I test the assumptions on a long-form dataset? I am asking this, because in the other video you tested the assumptions on a wide format dataset.
Thanks for the nice lecture, very clear explanations. Maybe, one note concerning the variance of the pH, Density, and Conductivity explanation. Should we consider the variance multidimensional, so that 78.9% and 68.4% refer to different dimensions?
Thanks for the video. It’s very helpful. I have a question about the output of lm() modeling at 50:28. Why can't we see 0-10 Depth category in the coefficients output whereas it is present in the dataset. There are just 10-30 , 30-60, and 60-90 in the output? Thank you.
for some reason, the ICC function did not work for me . When I ran :ICC(pt[,5:11]) This is the error message I got : Error in initializePtr() : function 'cholmod_factor_ldetA' not provided by package 'Matrix' What do I need to do to get this resolved. I have installed the psych package.
Good morning, First of all, cheers for the class. Very very simple to get to the point. I have a question: In the FACTORIAL MANOVA, what about having for instance 3 replicates per measures in depth…? So three replicates for the TOP 0-10, three for the TOP 10-30 etc...
Hello! Thank you so much for this video and the script! Would you indicate a literature reference for the Partial Eta-Squared Values calculation? Thank you!!
This video is really is a must-see for anyone self-studying multivariate analysis. Hope more excellent videos can be uploaded soon!

I had not seen your comment. I spent a few minutes looking for the MANOVA function in the mass package😅
Thank you so much! Really helpful 🙏
Excellent work!Please let's see a posthoc test, preferably DMRT/TUKEY.

Thanks a lot for your explanation, it is very useful. You should post more often, I really like it.
I will! I got 10 more videos on my list this year. 🙂

Excellent Video, very clearly explained

thanks for wonderful vedio.Would you please tell how to test assumptions for factorial Manova and if assumptions failed how to address that In r?

Does anyone know a way to test type 1 MANOVA? Unfortunately this command only accepts type II or III
very well explained. Detailed Demo.
for some reason, the ICC function did not work for me .
When I ran :ICC(pt[,5:11])
This is the error message I got :
Error in initializePtr() :
function 'cholmod_factor_ldetA' not provided by package 'Matrix'
What do I need to do to get this resolved. I have installed the psych package.
Thanks for sharing, very helpful, indeed!
very helpful! thankyou

Excelente, muchas gracias
How does the 4 test statistics of one-way manova vary?
