fitPFm: fitPFm

In LuchTiarna/PsyFuns: Package for extrapolating psychometric information

Description

Estimates parameters of psychometric function based on given data and settings with given algorithm.

Usage

fitPFm(formula, data, sigmoid, core, ..., split_by = NULL,
  type = "yes/no", algorithm = def)

Arguments

formula	Formula to identify important componets of data. Form is c(yes,no)~predictor for yes/no notation and c(PC,Observations)~predictor for Proportion correct notation.
sigmoid	determines the sigmoid of the fuction
core	dermines the core of the function
...	specifies the parametres for used fitting algorithm
split_by	specifies, whether and by which criteria should data be divided into subgroups (observers, sessions)
type	specifies type of data formating, proportion correct or yes/no
algrithm	specifies the algorithm to be used for fitting psychometric function parameters.

Value

vector of return values
