4-parameter logistic model
Dear R users
I'm a new user of R and I have a basic question about the 4-parameter
logistic model. According to the information from Pinheiro & Bates the model
is:
y(x)=theta1+(theta2-theta1)/(1+exp((theta3-x)/theta4)) ==
y(x)=A+(B-A)/(1+exp((xmid-input)/scal))
from the graph in page 518 of the book of the same authors (mixed models in
S) theta 1 corresponds to the horizontal asymptote
