samonDifferenceSummary {samon} | R Documentation |
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 )
