}The authors derive a general equation to compute multiple cut-offs on a total test score in order to classify individuals into more than two ordinal categories. The equation is derived from the multinomial logistic regression (MLR) model, which is an extension of the binary logistic regression (BLR) model to accommodate polytomous outcome variables. From this analytical procedure, cut-off scores are established at the test score (the predictor variable) at which an individual is as likely to be…

Clinical and parental classifications of obesity are divergent at extremes of the weight spectrum, with parents more likely to underestimate a child's weight if the child is black or South Asian, male, more deprived, or the child was older.
