Hosmer-Lemeshow goodness of fit test

Description

Internal, not usually called directly

Usage

metrics_hoslem(y, yhat, g = 10, digits = c(2, 3))

Arguments

y	Observed y, usually of the form fit$y.
yhat	Predicted y_hat, usually for the form fit$fitted
g	Number of bins to calculate quantiles.
digits	Number of decimal places of form c(2,3), where digits[1] is for chi-sq estimate and digits[2] is for p-value.

Value

Character string of chi-sq result, df, and p-value. Significant p-value suggests poor fit.
