Internal biglasso functions
loss.biglasso(y, yhat, family, eval.metric, grouped = TRUE)
The observed response vector.
The predicted response vector.
Either "gaussian" or "binomial", depending on the response.
The evaluation metric for the cross-validated error and
for choosing optimal lambda
. "default" for linear regression is MSE
(mean squared error), for logistic regression is misclassification error.
"MAPE", for linear regression only, is the Mean Absolute Percentage Error.
"auc", for logistic regression, is the area under the receiver operating
characteristic curve (ROC).
Whether to calculate loss for the entire CV fold
(TRUE
), or for predictions individually. Must be TRUE
when
eval.metric
is 'auc'.
