fun.diag1: Diagnostic function for theoretical distribution fits through the resample Kolmogorov-Smirnoff tests

Description

This function is primarily designed to be used for testing the fitted distribution with reference to a theoretical distribution. It is also tailored for output obtained from the fun.data.fit.ml function.

Usage

fun.diag1(result, test, no.test = 1000, alpha = 0.05)

Value

A vector showing the number of times the KS p-value is greater than alpha for each of the distribution fit strategy.

Arguments

result

Output from fun.data.fit.ml function.

test

Simulated observations from theoretical distribution, the length should be no.test\(\mbox{\textasciitilde}\)2.

no.test

Number of times to do the KS tests.

alpha

Significance level of KS test.
