relative.effect: Calculating relative effects

Description

Calculates the relative effects of pairs of treatments.

Usage

relative.effect(result, t1, t2 = c(), preserve.extra = TRUE)

Arguments

result

An object of class S3 mtc.result to derive the relative effects from

t1

A list of baselines to calculate a relative effects against. Will be extended to match the length of t2.

t2

A list of treatments to calculate the relative effects for. Will be extended to match the length of t1. If left empty and t1 is a single treatment, relative effects of all treatments except t1 will be calculated.

preserve.extra

Indicates whether to preserve extra parameters such as the sd.w and sd.d

Value

• Returns an mtc.results object containing the calculated relative effects.

network <- read.mtc.network(file)

# To save computation time we load the samples instead of running the model
results <- mtc.run(model)
file.samples <- system.file("extdata/luades-smoking.samples.gz", package="gemtc")
results <- read.mtc.result.samples(file.samples, model, "rjags")

# Creates a forest plot of the relative effects
