The default is "tuning"; in this case, the recommended tuning
parameter values are presented.
If "estimatedPT", then the estimated component loading and estimated
component score matrices (based on the recommended tuning paramter
values) are presented.
If "full", then information is displayed regarding 1) the
recommended tuning parameter values, 2) the estimated component
loading and estimated component score matrices (based on the
recommended tuning paramter values), 3) the proper region
for Lasso tuning parameter values, given a Group Lasso tuning
parameter value, 4) # of variable selected,
5) Predicted residual sum of squares (PRESS),
6) standard errors for PRESS, 7) Lasso and Group Lasso tuning
parameter values that have been evaluated.
