test.nb.inar1 {spass}

Testing Hypotheses in NB-INAR(1) model

Description

test.nb.inar1 tests hypotheses for rate ratios of two groups in an NB-INAR(1) model

Usage

test.nb.inar1(dataC, dataE, h0 = 1)

Arguments

dataC

a matrix or data frame containing count data from the control group. Columns correspond to time points, rows to observations.

dataE

a matrix or data frame containing count data from the experiment group. Columns correspond to time points, rows to observations.

h0

the value against which h is tested, see 'Details'.

Details

the function test.nb.inar1 tests for the null hypothesis \lambda_T/\lambda_C = h0 against the alternative \lambda_T/\lambda_C \neq h_0. For attaining estimates, method of moments estimators are used.

Value

test.nb.inar1 returns effect size, standard error, Z-statistic and p-value attained through standard normal approximation.

Source

test.nb.inar1 uses code contributed by Thomas Asendorf.
