In phenology: Tools to Manage a Parametric Function that Describes Phenology and More

Description

This function fits a model of internesting period.
The parameters are:

• meanIP : The average number of days between two nesting processes

• DeltameanIP : The shift in days for IP at each new clutch.

• sdIP : The standard deviation of number of days between two nesting processes

• minIP : The minimum number of days between two nesting processes

• pAbort : The -logit of the probability to abort a nesting process

• meanAbort : The average of the number of days after the abortion of a nesting process

• sdAbort : The standard deviation of the number of days after the abortion of a nesting process

• pCapture : The -logit of the probability to capture a female on the beach

• meanECF : The average number of clutch a female will try to do being reprensented as ECF

• sdECF : The standard deviation of number of clutch a female will try to do

• N : The number of replicates to generate the distribution (default is 10000 if not indicated)

• ECF.x : The relative proportion of females nesting with ECF = x (ECF.1 being fixed to 1)

Usage

IPModel(
  par,
  parallel = TRUE,
  limits = list(meanIP = 40, meanECF = 4, minIP = 15, sdAbort = 1, sdIP = 1, sdECF = 1,
    DeltameanIP = 0.5, maxDays = 365)
)

Arguments

par	Set of parameters
parallel	If TRUE, will use parallel computing
limits	A list of limits for various parameters

Details

IPModel estimates the pattern of internesting intervals for a set of parameters.

Value

Return a list with two elements.
