calc.deviance

Calculate deviance

Function to calculate deviance given two vectors of observed and predicted values. Requires a family argument which is set to binomial by default

calc.deviance(obs, pred, weights = rep(1,length(obs)), 
                family="binomial", calc.mean = TRUE)

`obs`	a vector with observed values
`pred`	a vector with predicted values that correspond the the values in obs
`weights`	a vector of weight values
`family`	One of "binomial", "bernoulli", "poisson", "laplace", or "gaussian"
`calc.mean`	Logical. If `TRUE`, the mean deviance is returned
