This is the logistic distribution of single random variable (taken from Wikipedia).
x = random variable mu = mean of all random variables s = variance.
Now, I want to do a Bivariate logistic distribution (having two random variables x1 and x2). My dataset is going to be image pixel values!
When I find the covariance of two random variables, it turns out to be a 2 x 2 square matrix but I need a single number! How to actually compute a bivariate model?
