Hello,
I have a basic regression model and I want to import a threshold price, so that the independent variable has two coefficients instead of one.
For example if we have the regression y=α+β*x what i want is to convert it in y= α+β*χ(if x>5)+γ*x(if x<5).
Thank you in advance.

Code: Select all
ls y c x*(x>5) x*(x<5)
The trick is that a logical condition yields a 1 if true and a 0 if false.

That works perfect thank u.
Re: Threshold Regression
In connection with the problem presented by Dusan, is it possible to perform a similar estimation where the threshold level is endogenously determined (and not Userdefined) along with the model's coefficients (single independent variable plus a constant)? Is there a simple procedure for estimating such a model by using Eviews?

Any advice would be strongly welcomed. Thanks.

Re: Threshold Regression
Hi,
Concerning Threshold regression, I want to replicate a result of a study on inflation and growth but I am new to software packages. I would be happy if anyone can help me with the steps involve in finding the threshold at which inflation spurs or hurts growth.
Thanks in advance.

Re: Threshold Regression
Perhaps lookup "threshold in the EViews help system.
