Win odds calculation using formula syntax

Description

Win odds calculation using formula syntax

Usage

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

Arguments

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

Value

a data frame containing the win odds and its confidence interval. It contains the following columns:

• WO calculated win odds.

• LCL lower confidence limit.

• UCL upper confidence limit.

• SE standard error of the 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 calculated win probability.

• WP_SE standard error of the win probability.

• WP_SD standard deviation of the win probability, calculated as WP_SE multiplied by sqrt(N).

• N total number of patients in the analysis.

• formula returning the specified formula in the x argument.

• ref showing how the reference group was selected. Can be modifying by specifying the ref argument.
