How to fit a logisitic function to a dataset

Postby azellou1 » Tue Dec 31, 2013 9:45 am

Hello:

I have a time series that looks like a logistic function and I would like to fit a logistic function to it. Is there a readily available program in EViews to do that?
Thank you for your help!

EViews is happy to do a nonlinear regression. For example,

Code: Select all

ls y = c(1)*exp(c(2)*t)/(1+exp(c(2)*t))
