metrics_hoslem

Hosmer-Lemeshow goodness of fit test

Internal, not usually called directly

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

`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.

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