calc.deviance: Calculate deviance

Description

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

Usage

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

Arguments

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
