Stratified win odds with adjustment using formula

Description

Stratified win odds with adjustment using formula

Usage

## S3 method for class 'formula'
stratWO(x, data, ...)

Arguments

x	an object of class formula.
data	a data frame.
...	additional parameters.

Value

a data frame containing the following columns:

• WO stratified (or adjusted/stratified) win odds.

• LCL lower confidence limit for adjusted (or adjusted/stratified) WO.

• UCL upper confidence limit for adjusted (or adjusted/stratified) WO.

• SE standard error of the adjusted (or adjusted/stratified) win odds.

• WOnull win odds of the null hypothesis (specified in the WOnull argument).

• alpha two-sided significance level for calculating the confidence interval (specified in the alpha argument).

• Pvalue p-value associated with testing the null hypothesis.

• WP adjusted (or adjusted/stratified) win probability.

• LCL_WP lower confidence limit for adjusted (or adjusted/stratified) WP.

• UCL_WP upper confidence limit for adjusted (or adjusted/stratified) WP.

• SE_WP standard error for the adjusted (or adjusted/stratified) win probability.

• SD_WP standard deviation of the adjusted (or adjusted/stratified) win probability.

• N total number of patients in the analysis.

• Type "STRATIFIED" or "STRATIFIED/ADJUSTED" depending on whether COVAR is specified.

Examples

# Example 1: Stratified win odds with covariate adjustment
stratWO(x = AVAL ~ TRTP + EGFRBL | STRATAN, data = KHCE)
# Example 2: Stratified win odds without covariate adjustment
stratWO(x = AVAL ~ TRTP | STRATAN, data = KHCE)
# Example 3: Only covariate adjustment (without stratification) is implemented in regWO()
regWO(x = AVAL ~ TRTP + EGFRBL, data = KHCE)
# Example 4: Non-standardized names
dat <- data.frame(response = KHCE$AVAL, treatment = KHCE$TRTP, 
covariate = KHCE$EGFRBL, group = KHCE$STRATAN)
stratWO(x = response ~ treatment + covariate | group, data = dat)
