samonDifferenceSummary: Summary function for the difference in treatment effect

In samon: Sensitivity Analysis for Missing Data

Summary function for the difference in treatment effect

Description

Produces a summary of the difference in treatment effect using two samon objects. It combines bootstrap and jackknife results to produce confidence intervals

Usage

samonDifferenceSummary( trt1, trt2, CIlevel = 0.95 )

Arguments

trt1	the result from a call to samonSummary
trt2	the result from a call to samonSummary
CIlevel	the confidence level for confidence intervals

Details

Combines estimates, bootstrap estimates and jackknife standard error estimates to produce summary estimates and confidence intervals for an estimate of the difference in treatment effect from two samon objects.

The difference in treatment estimates is taken to be those of treatment 2 minus those of treatment 1 at the same value of sensitivity parameter alpha.

Value

Returns a list. Items include: TM which contains treatment estimates, standard errors for these estimates, the estimate of their difference and estimates of the standard error of the difference. Also contains CI which contains confidence intervals. Other items are returned for convenience are n10, the number of subjects in the first treatment group, and n20 the number of subjects in the second treatment group.

Examples

# samon results for treatment 1 and 2 respectively:
data("P1Results")
data("P2Results")

Summary1 <- samonSummary( P1Results )
Summary2 <- samonSummary( P2Results )
SummaryD <- samonDifferenceSummary( Summary1, Summary2 )
SummaryX <- samonCrossSummary( Summary1, Summary2 )
