nullTest {dirmult}

Simulation based test for null-hypothesis, H0:theta=0

Description

Simulates data sets under the null-hypothesis, H_0:\theta=0. This corresponds to an ordinary multinomial model without any overdispersion. Based on the returned data frame simulated p-values may be computed.

Usage

nullTest(data, m=1000, prec=6)

Arguments

data

A matrix or table with counts. Rows represent subpopulations and columns the different categories of the data. Zero rows or columns are automaticly removed.

m

Number of simulated data tables.

prec

The tolerance of the iterations. Corresponds to epsilon=1e-prec in dirmult.

Value

Returns a data frame with theta estimates and log-likelihood values.
