In tohein/linearMTL: Linear Models for Multi-Task Learning

Compute linear predictions from predictor variables and regression coefficients.

1	MTPredict(LMTL.model, X = NULL, task.specific.features = list())

`LMTL.model`	Linear multi-task learning model (list containing B and intercept).
`X`	N by J1 matrix of features common to all tasks.
`task.specific.features`	Named list of features which are specific to each task. Each entry contains an N by J2 matrix for one particular task (where columns are features). List has to be ordered according to the columns of Y.
