Additionally, the outputs scores matrix U is linearly regressed against the inputs scores matrix T: (3c) where B holds the regression coefficients determined by minimising the residuals E U. Finally, the explained variance in target data (which in our case is flux data, R) by the model is given by the following equation: (4) with indexes i and j denoting observation and flux indexes respectively.
