Mean Square Error Normal Dependent (meansquare_nd)
Contents
Mean Square Error Normal Dependent. Mean Square error of Linear Loss with mutually dependent normally distributed random coefficients. It is calculated with Matrix of Means (one row matrix) and Covariance Symmetric Matrix
Syntax
meansquare_nd(matrix_mn,matrix_cov) |
short call; |
meansquare_nd_name(matrix_mn,matrix_cov) |
call with optional name. |
Parameters
matrix_mn is a PSG matrix of mean values:
where the header row contains names of variables. The second row contains numerical data.
matrix_cov is a PSG matrix of covariance values:
where the header row contains names of variables. Other rows contain numerical data.
Mathematical Definition
Mean Square Error Normal Dependent function is calculated as follows:
,
where
is a mean of the loss function,
is a variance of the loss function,
is Loss Function (See section Loss and Gain Functions);
is an argument of function.
