WS: WS: Wilson Score Method for Simultaneous Confidence Intervals

Description

Computes Wilson score-type simultaneous confidence intervals for multinomial proportions. The Wilson method improves upon the Wald interval by ensuring better coverage probabilities, especially for small samples or proportions near 0 or 1.

Usage

WS(inpmat, alpha)

Value

Prints the original and adjusted confidence intervals for each category, along with the volume (product of interval widths).

Arguments

inpmat

Integer vector of observed cell counts corresponding to a categorical dataset. All values must be non-negative.

alpha

Desired statistical significance level

Author

Dr. M. Subbiah

Details

This approach adjusts both the center and width of the confidence interval to account for the sampling distribution of proportions, leading to non-symmetric intervals that perform better than the simple Wald intervals.
