Compute_Risk

Location: ..\cubatch\Model_PARAFAC\private\Compute_Risk.m

function Validation = Compute_Risk (Hand,Model,Validation);

Description:
Computes the risk value and the MSE between the models obtained by resampling (leave one out and bootstrap) and the reference model, i.e. the one computed on the whole set of batches/samples.

Inputs:
Hand: at the first call is a vector of length 2, the first element is the total number of replicates in all the models, the second a counter for the replicate being processed. These two elements are moved to position 2 and 3 and the first element is the handle to the waitbar opened by this very function.
Model: ModelOut.model structure
Validation: ModelOut.validation structure

Outputs:
Validation: ModelOut.validation structure with an updated 'stats' field updated with the risk and the MSE

Called by:
Model_PARAFAC\Plot_RIP, Model_PARAFAC\Plot_Risk

Subroutines:
Internal: None
External: facoptscale, facperm, recfac
