I need to test if ratio variables made from uncorrellated/correlated
variables are correlated. I have three questions:
1) Should I generate uniformely distributed variables e.g. X=rand
(50,1) or normally distributed variables by using RANDN?
2) How can I generate a matrix of 50-by-1 containing numbers with a
predefined mean and variance?
3 Is it possible to predetrmine "the correlation level" of the
variables in the matrix. For example to create a matrix of 50-by-1
with correlation coeffecient of 0.70 (is this possible also if mean
and variance are predefinied)?
