Does anyone know if there is a repeated measures ANOVA function in the stats toolbox? anova1 is not the correct function and I am not sure if anovan can be used this way? I have one group of data that has been analysed several times, in SPSS or excel I would simply select 'repeated measures anova' but this is not appearing in MATLAB help - any ideas?
To provide a clearer example I have one group of temperature data (n=20) which is being measured at systemic time intervals (15 times). I have checked the old posts posts I can find via Google but cant quite seem to make sense of them.
I note that the Friedman test is availlable so I presume there is a parametric option?

Any/all help is greatly appreciated!!
Thanks
Dan

Dan, there is no repeated measures function in the Statistics Toolbox. If
you search on the file exchange you will find some things, such as

http://www.mathworks.com/matlabcentral/fileexchange/22088-repeated-measures-anova

I have not tried this myself, but I see it gets good ratings.

I am interested in this topic. Feel free to send e-mail to me if you want to
provide details on what you would like to see in the MathWorks toolbox. I
work on that.
