Fit Lactin model for development

Fits a function that returns parasitoid wasp development rate based on daily temperature

Usage

fit_lactin(epsilon, tau, lambda, Tupper)

Arguments

epsilon

development rate scalar

tau

development rate scalar

lambda

development rate scalar

Tupper

upper development threshold

Value

function that accepts x and returns y based on fitted model

Details

A development rate function to pass on to the Parasitoid model. Fits a curve using the Lactin model (Lactin et al. 1995): $$ e^{\epsilon \cdot T} - e^{\epsilon \cdot T_{\text{opt}} - \left(\frac{T_{\text{opt}} - T}{\tau}\right)} + \lambda $$
