In rmarceauwest/fiveSTAR: Run 5-STAR Algorithm

Estimate Risk Difference Within Strata

Description

Estimates risk difference and significance within each formed strata

Usage

ratediffbystrata(yy, arm, treeStrata, treetype = "final",
  termNodes = NULL, alternative = "two.sided", cilevel = 0.05,
  verbose = 0, plot = TRUE)

Arguments

yy	Case control status response vector
arm	Treatment indicator, 1 = test treatment, 0 = control
treeStrata	Vector of strata membership, as defined by ctree strata
treetype	String, whether trees input are "preliminary" or "final"
termNodes	Vector of names for each tree strata formed (e.g., number of strata or covariate definition)
alternative	For tests, whether alternative hypothesis is "less", "greater", or "two.sided" (default = "two.sided")
cilevel	Confidence level alpha for overall result and confidence intervals
verbose	Numeric variable indicating amount of information to print to the terminal (0 = nothing, 1 = notes only, 2 = notes and intermediate output)
plot	Logical, whether to create risk difference forest plots

Value

• fitsummary: summary of risk difference within each strata

• table: Summary of amalgamated risk difference estimate, variance, p-value, and cilevelx100% confidence interval assuming sample size weights

• weights: Sample size weights used to construct estimate
