Reg__OLSconstrained

R Documentation

Restricted OLS regression

Description

Restricted OLS regression

Usage

Reg__OLSconstrained(Y, X, Bcon, G = NULL)

Arguments

`Y`	left hand side variables (M x T)
`X`	regressors (i.e. N-1 variables + the intercept) (N x T)
`Bcon`	constraints matrix (M x N). If Bcon(i,j) = nan –> B(i,j) is a free parameter
`G`	weighting matrix (psd) - (M x M). Default is set to be identity

Details

Estimate of B is obtained by minimizing the objective: sum_t (Y_t-B X_t)' G^(-1) (Y_t-B*X_t) subject to the constraint that B = Bcon for all non-nan entries of Bcon

Value

matrix of coefficient (M x N)
