Calculate deviance

This function calculates the affine value T(y) of -2 log likelihood-ratio statistic which is also called the deviance

deviance(x, y, ...)

# S3 method for outlier_model
deviance(x, y, ...)

# S3 method for mixed_outlier
deviance(x, y, ...)

Arguments

x	A outlier_model object
y	An observation (named character vector). If x is of class mixed_outlier it should be a data.frame with two rows.
...	Not used (for S3 compatibility)

Value

The deviance test statistic of y based on the model x
