fitODBOD (version 1.5.3)

Overdispersion: Overdispersion

Description

After fitting the distribution using this function we can extract the overdispersion value. This function works for fitTriBin, fitBetaBin, fitKumBin, fitGHGBB and fitMcGBB for Binomial Mixture Distributions. Similarly, Alternate Binomial Distributions also support this function for fitAddBin,fitBetaCorrBin, fitCOMPBin, fitCorrBin and fitMultiBin.

Usage

Overdispersion(object)

Value

The output of Overdispersion gives a single value which is the overdispersion.

Arguments

object

An object from one of the classes of fitTB,fitBB,fitKB,fitGB,fitMB.

Details

Note : Only objects from classes of above mentioned classes can be used.

Examples

No.D.D=0:7      #assigning the random variables
Obs.fre.1=c(47,54,43,40,40,41,39,95)  #assigning the corresponding frequencies

#estimating mode value for given data
results<-EstMLETriBin(No.D.D,Obs.fre.1)
results
mode<-results$mode

#fitting the Triangular Bionomial distribution for estimated parameters
TriBin<-fitTriBin(No.D.D,Obs.fre.1,mode)
TriBin

#extracting the overdispersion
Overdispersion(TriBin)
