Continuous outcomes: * calculation of shrinkage for each criteria based on N needed in specific criteria

• also allowance for the unique scenario when starting N already meets shrinkage requirement set by user (this is more for academic exercise, as in practice a high shrinkage will be desired and so it is very rare that the base N (set to p+2) will provide good shrinkage)

Binary and TTE outcomes: * more informative error message added for rare scenario where shrinkge is specified lower than r-squared which results in NaNs from shrinkage formula
