form.table: Forming Basic Tables

In ehsanx/iptw: Inverse Probability of Treatment Weighting

Description

Forms the crude, stratified tables suitable for using in other functions of this package.

Usage

form.table(Y1A1L1, Y1A0L1, Y1A1L0, Y1A0L0, Y0A1L1, Y0A0L1, Y0A1L0, Y0A0L0)

Arguments

Y1A1L1	Frequency of subjects who are treated (A=1), exposed to confounder (L=1) and developed the outcome (Y=1).
Y1A0L1	Frequency of subjects who are not treated (A=0), but exposed to confounder (L=1) and developed the outcome (Y=1).
Y1A1L0	Frequency of subjects who are treated (A=1), unexposed to confounder (L=0) and developed the outcome (Y=1).
Y1A0L0	Frequency of subjects who are not treated (A=0), unexposed to confounder (L=0) and developed the outcome (Y=1).
Y0A1L1	Frequency of subjects who are treated (A=1), exposed to confounder (L=1) but did not developed the outcome (Y=0).
Y0A0L1	Frequency of subjects who are not treated (A=0), but exposed to confounder (L=1) and did not developed the outcome (Y=0).
Y0A1L0	Frequency of subjects who are treated (A=1), unexposed to confounder (L=0) and did not developed the outcome (Y=0).
Y0A0L0	Frequency of subjects who are untreated (A=0), unexposed to confounder (L=0) and did not developed the outcome (Y=0).

Details

Frequency of all possible subject combination is required to insert in this function. This function eventually generates tables suitable for using in all other functions in this package.

Value

data	List frequencies
crude.data	Combines all the frequencies in a 2x2 table of treatment vs. outcome
stratified.table	Crude table is stratified by condounder exposure
condounder.exposed.data	2x2 table only containing subjects exposed to confounder
condounder.unexposed.data	2x2 table only containing subjects unexposed to confounder
