Estimating K-factors for Tolerance Intervals Based on Howe's Method

Source: R/k_factor.R

Estimates k-factors for tolerance intervals based on Howe's method with normality assumption.

k_factor(n, alpha = 0.05, P = 0.99, side = 1)

Arguments

n

Sample size
alpha

The level chosen such that (1-alpha) is the confidence level.
P

The proportion of the population to be covered by the tolerance interval.
side

Whether a 1-sided or 2-sided tolerance interval is required (determined by side = 1 or side = 2, respectively).

Value

The estimated k-factor for tolerance intervals assuming normality.

Note

This function is a simplified version of tolerance::K.factor(), only considering Howe's method.
