computeTestKolmogorovGamma {rotRPackage} | R Documentation |
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 Gamma distribution of the given parameters and returns a list containing the result and test p-value.
computeTestKolmogorovGamma(numericalSample, k, lambda, gamma, testLevel = 0.95, estimatedParameters)
numericalSample |
the sample to be tested (numeric vector) |
k |
The Gamma distribution kParameter. |
lambda |
The Gamma distribution lambdaParameter. |
gamma |
The Gamma distribution gammaParameter. |
testLevel |
the test level. (scalar in [0:1]) |
estimatedParameters |
the test level. (scalar in [0:1]) |
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) |
