Hi everyone,
Does the selfstart function SSlogis of the "nlme" library allows the introduction of
time varying covariates ?
For example how can I interpret the xmid parameter (reperesenting the age at which we
reach the half of the asymptote) if I want to explain it by a some time varying
covariate?
Thanks in adavance,
Abderrahim
