my problem is that I cannot find any tests proposed on Matlab that allow me to run a paired t-test for samples with unequal sizes.
Thank you for your help !By definition a paired t-test is performed on two random samples of the same size . If they are not of the same size then you just can't do it.
You could instead compare if the samples come from the same distribution (or whatever it is your are trying to achieve) using a KS test or other some such (then again depending on what you want to actually do).
Math93 il 1 Ago 2017Basically I believe my samples are paired and unequal because I am testing the mean differences between two parts of one group of companies, using a sorting rule such as: sub sample one is made out of all companies < or = to . total assets, and sub sample two is made out of all companies >than . total assets which then gives me two sub-samples of different size but that I believed are still paired because they come from the sample primer sample.
