significance level in star format alongside coefficients

Posted: Mon Apr 27, 2020 7:57 am

Dear Sir,

Is it possible that in the output we can get the significance level in the format of ***, **, * alongside the coeffecients.

For example, when i run the following code

GARCH(P=1,Q=1,MV=BEKK,robusterrors,stdresids=rstd,DIST=GED) / Australia Brazil

The output comes as

Code: Select all

Variable	Coeff	Std Error	T-Stat	Signif
***************************	******************	*************	*************	*************
1.  Mean(AUSTRALIA)	0.000584627	0.000128704	4.54243	0.00000556
2.  Mean(BRAZIL)	0.000997754	0.000268607	3.71455	0.00020357

5.  C(2,2)	0.002007599	0.000242704	8.27179	0
6.  A(1,1)	0.246281767	0.02628357	9.37018	0
7.  A(1,2)	0.059276076	0.037605948	1.57624	0.11497003
8.  A(2,1)	0.001528008	0.0107063	0.14272	0.88651097
9.  A(2,2)	0.18415498	0.019661053	9.36649	0
10. B(1,1)	0.95150441	0.010673004	89.15057	0
11. B(1,2)	-0.015836893	0.014354128	-1.1033	0.26989741
12. B(2,1)	-0.003021841	0.003775102	-0.80047	0.42344088
13. B(2,2)	0.966697673	0.006554695	147.48171	0
14. Shape(GED)	1.769156737	0.06437566	27.48176	0
My quesion is how can we get the significance level as star alongside the coeffecient.

e.g. A(2,2) = 0.18415498***

That's what REPORT is for. The output from estimation instructions is generally not directly usable for publication since it shows way too many decimals and the combination of standard errors, t-stats and significance levels is (in practice) redundant---usually at most one of those ends up getting used (though which it is can vary from paper to paper). If it's just that you're trying to interpret the result, you should concentrate on the significance level column, where most are showing at 0's which is significant at any reasonable level.

This is an example of using a function to tag coefficients in a REPORT based upon the significance levels.

Hi Tom. I have a model with six stocks and I run a multivariate GARCH for each one. I want to use the REPORT instruction. I already have the report with coefficients and standard errors in parenthesis:

But how can I include the significance for each parameter in the REPORT instruction? The example you put in this section (signiftag), I don´t know how to adapt it to my exercise.

There's some sort of mismatch between your data file and your program as I get a

## SX11. Identifier MKPTFW is Not Recognizable. Incorrect Option Field or Parameter Order?

at the first regression. However, I'm not really sure what you're trying to get out of this. Those GARCH models are going to have probably a full page of output each. That doesn't strike me as something that you would publish with relatively little editing. As it says earlier, if you're doing this for *your* purposes, just read the significance level columns.
