Description

This function finds confidence intervals for relative risks and calculates the log-likelihood test. It is a method for the generic function summary of class nltm. It can be invoked by calling summary for an object of class nltm.

Usage

## S3 method for class 'nltm'
summary(object,  coef = TRUE, conf.int = 0.95, 
        digits = max(options()$digits - 4, 3),...)

Arguments

object

Fitted model object of class nltm. This is assumed to be the result of some function that produces an object with the same named components as that returned by the nltm function.

coef

If true it gives a table with coefficients, standard errors and p-values. Default is TRUE.

conf.int

Confidence level of confidence intervals for relative risks. If 0 confidence intervals are not computed. Default is 0.95.

digits

Number of digits used for formatting output.

...

Arguments to be passed to or from other methods.
