Structural Breaks with Confidence Intervals

Eviews has a nice set of Bai-Perron structural break tests.

But it doesn't provide confidence intervals around those break dates.

Is there any possibility that code exists to draws those bounds? thanks.

Re: Total system (balanced) observations

Thanks Glenn. Just one contextual follow up. I ask because replicating a paper where there's 21 data points and 5 estimable parameters and cross-quation parameter constraints. To me this appears to have a mere 21-5=16 dof! However the author says that since he’s estimating a system of 3 equations he...

Total system (balanced) observations

If, for example, you estimate a system of 3 equations in eviews with 35 data points eviews writes: Included observations: 35 Total system (balanced) observations 105 the last part is clearly 3*35. But why does e-views declare this. is it suggesting that estimating in a system is increasing your degr...

Bootstrap Non Linear System

I have a system of three equations which are non linear and have cross-equation parameter constraints. Is it possible in E-Views to perform a bootsrap procedure to derive bootstrapped parameter standard errors?

thanks.

system with AR errors

I’m estimating some non-linear equations by the system estimators. I want to allow for AR and/or MA errors in the individual equations.

This doesn’t seem to be possible going through the menu estimation. Is it otherwise doable?

Thanks.

Re: Stochastic Model Solution Inversion

Thanks. This worked a treat. It sounds like you're trying to change which variables are endogenous in the model. You talk about making z1 endogenous, but you would also need to change one of the variables that is currently endogenous (y1 or y2) into an exogenous variable (otherwise you would have tw...

Stochastic Model Solution Inversion

I want to perform the following operation on a model object. Say I have an estimated non-linear model: y1 = f(y2,x1,x2; coefs)+u1 y2 = g(y1,x1,x2; coefs)+u2 …. Assume x1 is a simple exog vble, in my case a parameter times a trend: x1= gamma*t . But now assume I want to solve the previously estimated...

SUR and iterated SUR

What’s the difference between SUR and iterated SUR? I know the latter iterates on the weighting matrix and coefficient vector either simultaneously or sequentially. That suggests to me that is should perform better than non-iterated SUR. And yet non-iterated SUR is the default option marked when you...

Unit Root Panel tests

I'm estimating a 5-equation time-series system and thus retrieving 5 time-series residuals for each equation. I'm interesting in testing for the stationarity of these residuals. I see e-views offers panel unit root test (e.g., IPS, ADF, PP). Are these tests somehow reserved for an original panel est...

Full Info ML vs. SUR

I have a 3-eqn non linear system. When I estimate with ML I get convergence and plausible results. When I estimate with my preferred SUR estimator I get "Log of a Non Positive Number" error. I've tried varying the initial parameter conditions (e.g., setting them to the ML estimates) but I ...

graphs overlay

I have 2 graphics files of histograms. for visual effect, i'd like to overlay them. I can do this by opening the files simultaneously and manually dragging them on top of one another. But it's a messy business. is there an automated way of doing this?

thanks.

Math characters in eps graph files

i've noticed that if i choose the mathematica fonts option in an eviews graphi can insert math charaters (e.g., lambda). when i save the resulting file as an eps and then include in a tex file, i find the maths format has vanished. For example the lambda which showed up correctly as the Greek symbol...
