I am new to statistics. I decided to use Kendall tau correlation.
I want to find correlations between every variable of the data set. (For example, if there are three variables in the data $x, y$ and $z$, then I need the correlations between $x$and $y$, $y$ and $z$, and $x$ and $z$.)
I have about 100 variables.
I am unable to find any example with the correlation between more than two variables.
Question 1 Is the method to find the correlation between more than two variables the same as that for two variables?
Question 2 Some of my variables can be qualitative. Does Kendall tau satisfy my requirement? Please suggest any better method to do it.
Please suggest to me some readings about Kendall tau correlation.
