Arguments

param

vector of numbers. Parameters of the 5PL curve.

t

numeric vector. Log concentrations.

x

numeric vector. Concentrations.

y

numeric vector. Response.

sd.e

sd.e

tao

vector of numbers or single number. Effective doses. Vectorized for this argument.

expy

Boolean. Controls whether to exponentiate y

gamma

power variance function parameter

Details

FivePL.t and other functions are vectorized for the x and the y arguments.

Four parameterizations are implemented. Classical: b,c,d,e,f gh: c,d,f,g,h ED50: c,d,f,b,tao(ED50) ED50b: c,d,f,h,tao(ED50). This is called tao-h in Cumberland et al. (2014)

Examples

FivePL.t(5:6, p.eotaxin[1,])

FivePL.x.inv(c(4,5,11), p.eotaxin[1,])
