Uniform Tolerance Intervals

Description

Provides 1-sided tolerance intervals for data distributed according to a uniform distribution.

Usage

uniftol.int(x, alpha = 0.05, P = 0.99)

Arguments

x A vector of data which is distributed according to a uniform distribution.
alpha The level chosen such that 1-alpha is the confidence level.
P The proportion of the population to be covered by this tolerance interval.

Value

uniftol.int returns a data frame with items:

alpha The specified significance level.
P The proportion of the population covered by this tolerance interval.
1-sided.lower The 1-sided lower tolerance bound.
1-sided.upper The 1-sided upper tolerance bound.

Examples

 

## 90%/90% 1-sided uniform tolerance intervals for a sample
## of size 50. 

set.seed(100)
x <- runif(50, 0, 50)
out <- uniftol.int(x = x, alpha = 0.10, P = 0.90) 
out

plottol(out, x, plot.type = "hist", side = "two", 
        x.lab = "Uniform Data")
