Calculates the zero-inflation part of a hurdle exponential kernel.

Given the probability of an adult mosquito to stay in the same patch throughout its whole lifespan, and its mortality, it calculates the height of the pulse-density part of the hurdle kernel.

calcZeroInflation(stayThroughLifespanProbability, adultMortality)

Arguments

stayThroughLifespanProbability

Probability of a mosquito to spend its whole lifespan in the same node
adultMortality

Adult mortality rate

Examples

# setup distance matrix
# two-column matrix with latitude/longitude, in degrees
latLong = cbind(runif(n = 5, min = 0, max = 90),
                runif(n = 5, min = 0, max = 180))

# Vincenty Ellipsoid  distance formula
distMat = calcVinEll(latLongs = latLong)

# get hurdle height
# Lets assume 80% stay probs and adult mortality of 0.1
hHeight <- calcZeroInflation(stayThroughLifespanProbability = 0.80,
                             adultMortality = 0.1)

# calculate hurdle exponential distribution over distances
kernMat = calcHurdleExpKernel(distMat = distMat, rate = 10, p0 = hHeight)
