Dear All:
I am doing the following matrix calculation:
. matrix alpha_head_t = (1/650) * (I - B*(invsym(B'*B))*B')* Sigma_a * (I-B*(invsym(B'*B))*B')
. matrix teststatisticbasic = alpha' * invsym(alpha_head_t) * alpha
matrix not symmetric
matrix not symmetric
r(505);
alpha_head_t is a matrix with 25 rows and 25 columns
alpha is a matrix with 25 rows and one column .
Does anyone know how to solve this issue?
Many Thanks!
