deoptim_fixed_gamma: deoptim

In LuchTiarna/PsyFuns: Package for extrapolating psychometric information

Description

Algorithm using deoptim method to increase precision of fitting psychometric function parameters . Version of algorithm with fixed gamma parameter. Gamma has to be specifed.

Usage

deoptim_fixed_gamma(data, sigmoid, core, gamma = 0.05, par = NULL,
  fn = NULL, gr = NULL, ..., method = c("Nelder-Mead", "BFGS", "CG",
  "L-BFGS-B", "SANN", "Brent"), lower = -Inf, upper = Inf,
  control = list(), hessian = FALSE)

Arguments

data	Specifies the data set on which the function will be fitted. Data have to be formated in specified way - data.frame/tibble (yes, no, predictor columns).
sigmoid	determines the outer shape of the fuction
core	dermines scalling of predictor
gamma	sets the loves boundary of function
...	specifies the parametres of optim function

Value

vector of return values
