glm.diag {boot}  R Documentation 
Generalized Linear Model Diagnostics
Description
Calculates jackknife deviance residuals, standardized deviance residuals, standardized Pearson residuals, approximate Cook statistic, leverage and estimated dispersion.
Usage
glm.diag(glmfit)
Arguments
glmfit 

Value
Returns a list with the following components
res 
The vector of jackknife deviance residuals. 
rd 
The vector of standardized deviance residuals. 
rp 
The vector of standardized Pearson residuals. 
cook 
The vector of approximate Cook statistics. 
h 
The vector of leverages of the observations. 
sd 
The value used to standardize the residuals. This is the estimate of residual standard deviation in the Gaussian family and is the square root of the estimated shape parameter in the Gamma family. In all other cases it is 1.
