dticksModel: Probability That a Fawn Belongs to a Given Tick Burden Class

In ClementCalenge/tickTF: Infection of Roe Deer Fawns by Ticks from 1992 to 2018 in the Trois-Fontaines Forest

Description

This function gives the probability that a fawn belongs to one of the three tick-burden classes (1 = less that 10 ticks; 2 = between 10 and 20 ticks; 3 = more than 20 ticks), given that the number of ticks follows a negative binomial distribution.

Usage

dticksModel(x, lambda, phi)

Arguments

x	a vector of integer values comprised between 1 and 3, giving the tick burden classes for the roe deer fawn.
lambda	a vector of the same length as x containing the mean of the negative binomial distribution for each value of x.
phi	a real number. The dispersion parameter of the negative binomial distribution.

Value

A real value corresponding to the probability of x
