Calculate time-dependent meanSource:
Calculate the expected value of each feature.
Matrix of coefficients from the spline fits, where rows correspond to features and columns correspond to variables in the model.
Vector of values of the periodic variable for the observations, where 0 corresponds to the lowest possible value and 1 corresponds to the highest possible value.
Period for the periodic variable.
Optional vector of knots. This argument is designed for internal use.
Matrix of predicted measurements, where rows correspond to time-points and columns correspond to features.
