STRN: Estimate the parameters that best describe the sexualisation thermal reaction norm within the TSP

Description

Estimate the parameters that best describe the sexualisation thermal reaction norm within the TSP. The Temperatures parameter is a character string which can be:
  • TimeWeighted.temperature.mean
  • TSP.TimeWeighted.temperature.mean
  • TSP.MassWeighted.temperature.mean
  • TSP.STRNWeighted.temperature.mean
  • TSP.MassWeighted.STRNWeighted.temperature.mean
  • MiddleThird.TimeWeighted.temperature.mean

Usage

STRN(Initial_STRN = NULL, EmbryoGrowthTRN = stop("Embryo Growth Thermal Reaction Norm must be provided"), tsd = stop("A result from the function tsd() must be provided"), Sexed = NULL, Males = NULL, Females = NULL, Temperatures = "TSP.MassWeighted.STRNWeighted.temperature.mean", ...)

Arguments

Initial_STRN
Values for initial model of Sexualisation Thermal Reaction Norm
EmbryoGrowthTRN
The Embryo growth Thermal Reaction Normal obtained with searchR()
tsd
The model used to predict sex ratio, obtained from tsd()
Sexed
The number of sexed embryos
Males
The number of males embryos
Females
The number of females embryos
Temperatures
The temperature from out of info.nests to be used
...
Parameters used for optim()

Value

The list with object return by optim()
