I can't even find this model with Google. Can you give me more information?

Best wishes, David Booth

Finally found it. Not much info but take a look at this link:

https://www.google.com/search?q=Complex+Biparametric+Pearson+Regression+Models+&ie=utf-8&oe=utf-8&client=firefox-b-1

and

Thank You so much Mr. David for your respon,,

I had searched about this model all day long in google too but have not gotten the package or R code..

But 3 days ago I had send a message to Ms. Maria who have written an article about CBP,,

She gave me code in R as a solution for my problem,,,

Thank you,,
