Description

This function calculates Risk Ratio and has 6 methods implemented leveraging pairwiseCI and metafor packags; Further inverse sinh base and adjusted are made available.

Usage

Association.Measures.RR(ai, bi, ci, di, alp, c1, c2, c3, c4)

Arguments

ai	- Numeric value representing True Positives
bi	- Numeric value representing False Positives
ci	- Numeric value representing False Negatives
di	- Numeric value representing True Negatives
alp	- Numeric value representing required significance level
c1	- Numeric value representing adjustment factor for inverse Sinh adjusted
c2	- Numeric value representing adjustment factor for inverse Sinh adjusted
c3	- Numeric value representing adjustment factor for inverse Sinh adjusted
c4	- Numeric value representing adjustment factor for inverse Sinh adjusted

Details

Two methods from pairwiseCI package and two methods from metafor package is implemented along with inverese Sinh and inverse Sinh adjusted with consistant output view. Methods implemented are Woolf, Gart, MI_NU, MOVER, Inverse Sinh and Inverse Sinh Adjusted.

Value

A dataframe with
