Extract call

, Gamma
from object
. And append mse
, p-value and the standard error of estimated coefficient.
The mean squared error mse
is defined as 1/n∑_{i=1}^n||Y_i-\hat{Y}_i||_F^2, where \hat{Y}_i is the prediction and ||\cdot||_F is the Frobenius norm of tensor.
Since the p-value and standard error depend on the estimation of cov^{-1}(vec(X)) which is unavailable for the ultra-high dimensional vec(X) in tensor predictor regression (TPR), the two statistics are only provided for the object returned from TRR.fit
.
print.summary.Tenv
provides a more readable form of the statistics contained in summary.Tenv
. If object
is returned from TRR.fit
, then p-val
and se
are also returned.
