gofRand: randomization test for goodness of fit

In helophilus/ColsTools: A variety of convenience tools and short-cuts

Description

gofRand(exp, obs, perm = 1000)

Usage

gofRand(obs, exp, perm = 1000)

Arguments

obs	a vector of observed frequencies
exp	a vector of expected frequencies, proportions, percentages or relative values
perm	number of randomizations

Details

produces a p-value from proportion of random data sets which result in a chi-squared value at least as big as that calculated from the actual data. Similar to the simulate.p.value option in chisq.test

Value

list of output variables;

randomisation p-value = calculated p-value from randomization

original chi-squared = chi-squared calculated from actual data

chi-squared distrib. p = p-value from chi-squared distribution; for comparison

number of permutations

Examples

Exp = c(9,3,3,1)
Obs = c(80,35,25,10)
gofRand(Obs,Exp)
