### Re: Basic Rolling Regression

Hello again, I'd really appreciate any advice. So, i have 230 series y: y1, y2, y3...y230. I want to estimate the equation ls y{!i} c x. (each of y on a constant and a serie x) Then i want to estimate a break date using Quandt Andrews test and store the break date of this test. After having the brea...

### Re: Basic Rolling Regression

Hello Gareth,

Thank you for your help. Well i could use Chow test if i know my breakdate. But in my case, i don't know the break date.

What do you suggest as other structural break test?

Thank you!

### Re: Basic Rolling Regression

Hello, Is it possible to perform Bai-Perron test with one maximum break , store the breakdate and then estimate rolling regression on the periode before the break date and the period after the breakdate? And then compare their means? I know it sounds complicated but maybe someone before has done it ...

### Re: Bai and Perron multiple break test

Hello Gareth, I have 9 dependent variables (y1...y9) and one independent variable (z). I would like to estimate a break least square (for each of the y on z) and store breakdate, coefficients of regression and the t-stat. (Y{!i}= constant + bz) The problem is that: for y3 for example i don't have a ...

### Re: Least Squares with Breakpoints

Hello, Does anyone know how can i store the break date of a "least squares with breakpoints". In fact i'm performing a least squares with a max one breakpoint : "equation eq1.breakls(maxbreaks=1) y c x" but i would like to know if i can store the breakdate and the 2 coefficients?...

Hello,

I am using Eviews 9 and I keep getting this result "Optimization failed: unable to evaluate objective at optimization starting values." and my rhos are all "NA."

Could you please help?

### Re: Basic Rolling Regression

thank you for your reply.

I see how to write a loop that loops over the stocks and runs a simple regression but i don't see how to do it with a rolling regression.

I don't see how to do it.

can you give me a simple example?

### Re: Basic Rolling Regression

Hello Gareth,

Thank you for the code.

I'm interested by running a rolling regression (with one explanatory variable) but for 35 stocks.

I have 35 stocks (Y1,Y2...Y35) and one market index (X).

Is it possible ?

Thank you
