Assigns signs to prior weights to obtain prior coefficients
Arguments
- y
target: vector of length \(n\) (see
family)- X
features: matrix with \(n\) rows (samples) and \(p\) columns (features)
- prior
prior coefficients: matrix with \(p\) rows (features) and \(k\) columns (sources of co-data)
- family
character "gaussian" (\(y\): real numbers), "binomial" (\(y\): 0s and 1s), or "poisson" (\(y\): non-negative integers);
- foldid
fold identifiers: vector of length \(n\) with entries from 1 to `nfolds`
- nfolds
number of folds: positive integer
- track
show intermediate output (messages and plots): logical
