weibull_link

Back to Functions

link = weibull_link(K,guessing,lapsing)

Weibull link in cell form for use with GLMFIT, GLMVAL and other Matlab GLM functions.

The guessing rate and lapsing rate are fixed, and power parameter is set to be equal K, hence link is a function of only one variable.

Input:

K: power parameter for Weibull link function

Optional input:

guessing: guessing rate; default is 0

lapsing: lapsing rate; default is 0

Output:

link: Weibull link for use in all GLM functions; cell with 3 entries:

  • weibullkFL: link function
  • weibullkFD: derivative
  • weibullkFI: inverse link
