Mean Square Error Normal Dependent (meansquare_nd_err)

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_err(matrix_mn,matrix_cov)

short call;

meansquare_nd_err_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.

 

Output

When function Mean Square Error Normal Dependent is used in optimization or calculation problems PSG automatically calculates and includes in the solution report two outputs:

 

pseudo_R2_function_name

coefficient of determination;

contributions(function_name)

normalized increments.

 

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.
