get_pvalue: Calculate the p-value associated with the W statistic

In chrsshn/checknormality: Check the Normality of Data Using Statistical Tests

Description

This function uses interpolation to calculate the exact p-value using the Shapiro-Wilk p-value table. Note that this is specific for p-values using the original or modified Shapiro-Wilk approach. P-values < 0.01 are reported as "0.001", and p-values > 0.99 are reported as "0.999".

Usage

get_pvalue(W, n, use_harmonic = T)

Arguments

W	the test statistic for the Shapiro-Wilk test; double, between 0 and 1
n	the number of data points; integer
use_harmonic	whether or not to use harmonic interpolation; boolean, 0 corresponding to linear interpolation and 1 corresponding to harmonic interpolation

Value

p-value, double

Examples

get_pvalue (.970, 20)
