    %% Compute Estimation Loss for NCA Model
%%
% Load the sample data.
load ionosphere

%%
% The data set has 34 continuous predictors. The response variable is the
% radar returns labelled as b (bad) or g (good). 

%%
% Perform neighborhood component analysis (NCA) to detect the important
% predictors in correctly classifying the radar returns with default
% settings.
mdl = fscnca(X,Y,'Verbose',1);

%%
% Compute prediction loss for the NCA model.
L = loss(mdl,X,Y)
