Re: Unstable GMM results

Possibly. How would I have to modify my code to use similar starting values as in the manual recalculation and thus arrive at the same estimation of the coefficient? Thank you.

Re: Unstable GMM results

Hi Gareth, thank you very much for your reply. I have amended the equation command to allow for multiple iterations: equation eq{!i}.GMM(INSTWGT=HAC,DERIV=an,method=nstep,gmmiter=1000,wscale="eviews",m=1000,c=0.0001,l=1000,showopts,cov="hac",covlag="a") [equation] @ [in...

Unstable GMM results

I have estimated 100 GMM equations using a program that loops over such a line of code: equation eq{!i}.GMM(INSTWGT=HAC,GMMITER=1,DERIV=AA) [equation] @ [instruments] For some of the 100 cases the coefficient estimates calculated by Eviews are implausible: Eviews shows a negative coefficient while a...

@prob data member of coefficient in equation object missing?

Going through the data members of the equation object in the Object Reference manual I can find @coefs(i), @tstats(i) but not @prob(i). Is there a data member for the probability value of a coefficient in the equation object? If not, what would be the most convenient way of obtaining this probabilit...

Re: Batch import using SQL command

Thank you Glenn. I have found the documentation of the import command in the Command and Programming Reference PDF file.

Re: Batch import using SQL command

Hi Chris, thank you very much. Using a program really seems like the right way to avoid this problem. When putting the command into a program file I get the following error message in a popup window: "Incomplete date specification (no start date provided) in "IMPORT "MYDSNFILE.DSN&quo...

Re: Batch import using SQL command

Hi Chris, thank you for your answer. I think your answer goes into the right direction. However, one issue remains which prevents me from fully automating the data import: After entering your suggested command in the command prompt, the "ODBC Dsn Read - Step 1 of 1" window pops up where I ...

Batch GMM estimation

I would like to like to run GMM estimations on several hundred series, one at a time. For instance, I would be using a command similar to gmmc.gmm(instwgt=white,gmmiter=2,nodf) cons c1 y1 y1(-1) w1 @ c1 p1(-1) k1(-1) x1(-1) gmmc.gmm(instwgt=white,gmmiter=2,nodf) cons c2 y2 y2(-1) w2 @ c2 p2(-1) k2(-...

Batch import using SQL command

I have time series of several hundred stocks stored in a MySQL database. I would like to import the time series data of each stock into an individual series in Eviews. To do this in an efficient way I am looking for some code which can be executed from the command line in Eviews and which would look...
