I have a function X, and two different approximator functions A and B (A-X) is Gaussian (or at least appears to be from mean, variance, skew and kurtosis calculations) with zero mean and variance of Va (B-X) is Gaussian (or at least appears to be from mean, variance, skew and kurtosis calculation

correlation of dependent variables

If I have 3 variables defined as follows: A, B as independent, uncorrelated values of 0 or 1 C defined as the logical AND of A&B, such that C=1 if and only if both A & B =1, and 0 otherwise. Example A=1, B=0 then C=0 A=0, B=1 then C=0 A=0, B=1 then C=0 A=1, B=1 then C=1 My question is, what is
