PLS = partial least squares regression; MPLS = modified partial least squares regression, Bayes RR = Bayes ridge regression; R2 = coefficient of determination calculated as the square of the correlation between observed and predicted values; DIC = deviance information criterion; pD/Terms = effective number of parameters/number of MPLS or PLS terms.

RCT = rennet coagulation time, min; CYCURD = cheese yield, weight of fresh curd as a percentage of the milk processed by weight; RECPROTEIN = recovery of protein, protein of the curd as a percentage of the protein of the milk processed; RECFAT = recovery of fat, fat of the curd as a percentage of the fat of the milk processed.
