In episensr: Basic Sensitivity Analysis of Epidemiological Results

Bounding the bias limits of unmeasured confounding.

Description

Function to elicit the limits on measures of effect corrected for an unmeasured confounder when only some of the bias parameters are known. Crude relative risk between exposure and outcome has minimally to be provided. Up to 3 other parameters can be entered.

Usage

confounders.limit(p = NA, RR = NA, OR = NA, crude.RR = NULL)

Arguments

p	Proportion with the confounder among the unexposed group.
RR	Relative risk between the confounder and the outcome.
OR	Odds ratio between the confounder and the outcome.
crude.RR	Crude relative risk between the exposure and the outcome.

Value

A list with elements:

model	Bias analysis performed.
bias.parms	Input bias parameters.
adj.measures	Output results.
