numofcell {HyetosMinute}R Documentation

The number of cells per storm, the sequence of time windows within the cell origins are produced, the vector of parameter η

Description

The function numofcell uses parameters α,ν,κ,φ of Bartlett-Lewis model in order to produce the number of cells per storm, the time windows within the cell origins are produced and the vector of parameters η.

Usage

numofcell(n,a,v,k,f)

Arguments

n

A positive integer that specifies the number of storms.

a

A positive number that specifies the shape parameter α of gamma distribution.

v

A positive number that specifies the scale parameter ν of gamma distribution.

k

Constant κ=β/η.

f

Constant φ=γ/η.

Details

In the original version of the model (Bartlett-Lewis Rectangular Pulse Model), all model parameters are assumed constant. In the modified version (Random Parameter Bartlett-Lewis Rectangular Pulse Model), the parameter η is randomly varied from storm to storm with a gamma distribution with shape parameter α (argument a) and scale parameter ν (argument v). Subsequently, parameters β and γ also vary so that the ratios κ=β/η (argument k) and φ=γ/η (argument f) are constant.

Value

NumofCells

Number of cells per storm.

TimeWindows

Time windows containing cell arrivals.

par.hta

Parameter η of exponential distribution governing cell durations of each storm. See details
