computeTestKolmogorovExponential {rotRPackage}R Documentation

Compute the Kolmogorov-Smirnoff test on a Exponential Distribution sample.

Description

This ROT function, called from a Test C++ object, is given a sample, a point, the necessary distribution parameters and optionnaly a test level. It then returns the result of a K-S test against the null hypothesis that the sample has un underlying Exponential distribution of the given parameters and returns a list containing the result and test p-value.

Usage

computeTestKolmogorovExponential(numericalSample, lambda, gamma, testLevel = 0.95, estimatedParameters)

Arguments

numericalSample the sample to be tested (numeric vector)
lambda The Exponential distribution lambda.
gamma The Exponential distribution gammaParameter.
testLevel the test level. (scalar in [0:1])
estimatedParameters the test level. (scalar in [0:1])

Value

A list is returned, containing :

testResult The result. 1 means H0 is not rejected. (scalar)
threshold The threshold applied to the p-value when deciding the outcome of the test.
pValue The test p-value. (scalar)

Examples

# Standard Exponential distribution example. 

print(computeTestKolmogorovExponential(rexp(1000, 3), 3, 0))
print(computeTestKolmogorovExponential(rexp(1000, 2.5), 3, 0))

# Non - Standard Exponential distribution example. 

print(computeTestKolmogorovExponential(rexp(1000, 3) + 1, 3, 1))
print(computeTestKolmogorovExponential(rexp(1000, 3) + 1, 3, 0.5))
