samon (version 4.0.2)

samonCrossSummary: Summary function for the difference in effect of two treatments at different sensitivity parameters alpha.

Description

Produces a summary of the difference in treatment effect using two samonSummary objects. Differences and confidence intervals are produced for each pair of sensitivity parameters.

Usage

samonCrossSummary( trt1, trt2, CIlevel = 0.95 )

Value

Returns a list. Items include TM which contains treatment estimates, their difference, and, standard error estimates and 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.

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 estimates to produce summary estimates and confidence intervals for the difference in estimates between two treatment groups. The difference is computed for all combinations of the smoothing parameter alpha found in the Sum1 input object.

The difference in treatment estimates is taken to be those of treatment 2 minus those of treatment 1.

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 )
