piecewise regression

You failed to specify 2 crucial issues: Are the join points known
(linear rgression, splines) or unknown (nonlinear regression)? And as
several have already indicated, what are the smoothness constraints?

Hello everybody!!!!

Quick question, if you'd like to throw a little tip:
?does anyone knows a function that runs piecewise regression models with
coefficients estimation and inferences ?

Thank you
