chi.gof2: Goodness of Fit Test for Poisson/Binomial

In adoocavo/Rstat_M1: Basic Statistical Methods in R

Goodness of Fit Test for Poisson/Binomial

Description

Goodness of Fit Test for Poisson/Binomial from a Frequency Table

Usage

chi.gof2(tab, para, para2, dist = "pois", mc1, mc2, alp = 0.05,
  dig = 2, dig2 = 4)

Arguments

tab	Table of frequency
para	First parameter (Poisson: mean, Binomial: sample size)
para2	Second parameter (Poisson: none, Binomial: probability)
dist	Distribution name ('pois' or 'binom'), Default: 'pois'
mc1	Sequential column numbers to merge (first set, lower side)
mc2	Sequential column numbers to merge (second set, upper side)
alp	Level of significance, Default: 0.05
dig	Number of digits below the decimal point for the table, Default: 2
dig2	Number of digits below the decimal point for the results, Default: 4

Value

list(stat=test stat, df=degree of freedom, crv=critical value, pv=p-value, tab=table)

Examples

# Goodness-of-fit Test (Poisson/Binomial)
set.seed(1234)
x=rpois(100,5)
mytab=table(x)
chi.gof2(mytab, 5)
chi.gof2(mytab)
chi.gof2(mytab, 10, 0.5, dist="binom")
chi.gof2(mytab, 10, dist="binom")
chi.gof2(mytab, mc1=8:9)
