I am conducting a t-test and have to choose between an unmatched and matched test. I am looking at the vaccination percentage rate between men and women in a given year. Would this be a matched test? My understanding is that in a matched test, the two variables need to be independent, but I am...
2. ### Regularized Canonical Correlation Analysis

Hi, I have a question about sample size and regularized canonical correlation analysis. Is a sample size of 15 unreasonable to use in a regularized canonical correlation analysis? If one has lots and lots of potential explanatory variables (multicollinearity expected) and multiple response...
3. ### Canonical Correlation (Package CCA)

Hi there, I'm using R (and package CCA) trying to perform a regularized canonical correlation analysis (There are 12-13 "response" variables in one dataset, another dataset of a whole lot (i.e. >400) of potential "explanatory" variables, but only a sample size of 15). Gonzalez et al. (2008...
4. ### Joint and Marginal Densities.

I am having some problems grasping the concept of these joint and marginal densities. It would really help if someone could provide me with an answer for the following question: Find the joint and marginal densities corresponding to the cdf F(X, Y) = (1 - е^αx){1-e^βy), x > 0, y>0, α >...
