VARResults.orth_ma_rep(maxn=10, P=None)¶

Compute orthogonalized MA coefficient matrices using P matrix such that \(\Sigma_u = PP^\prime\). P defaults to the Cholesky decomposition of \(\Sigma_u\)

Parameters:¶

maxnint

Number of coefficient matrices to compute

Pndarray (k x k), optional

Matrix such that Sigma_u = PP’, defaults to Cholesky descomp

Returns:¶

coefsndarray (maxn x k x k)
