I am using SPGRAPH to create a matrix of graphs. The larger I make the horizontal dimension (hfield=4,vfield=1 in my example), the less the headers of the individual graphs appear centered. Please see the figure attached. How can I solve that? Many thanks in advance.

Hi, I calculate marginal effects from an estimated probit model and struggle with the XVECTOR option of the PRJ instruction. It works fine for the ATMEAN option, prj(atmean,dist=probit), but not if I enter the vector of means manually, prj(xvector=||mean1,mean2,mean3,...||,dist=probit). Shouldn't th...

Dear all, I am plotting impulse respons functions. I want to plot the mean response (beta) and two alternative confidence bands: graph(nodates,number=0,ovcount=2,overlay=fan,ovsame) 5 # beta / 5 # upper1 / 8 # lower1 / 8 # upper2 / 8 # lower2 / 8 In this graph, one pair is shown as a fan chart, the ...

Benati constructs counterfactuals based on sign restrictions:

Thanks for your help!

Tom,

Do you have an idea about how to do it with sign restrictions? There, every accepted draw has to be neutralized by the shutdown shock.

Thanks again

Dear Tom, Are you aware of RATS codes on a VAR with an interaction term? Like in this example http://www.norges-bank.no/pages/95985/Norges_Bank_Working_Paper2013_17.pdf where the responses of the endogenous variables to a shock depend on the (exogenous) level of uncertainty. Thanks for your help Peter

Fantastic, thanks a lot, Tom

Dear Tom, Is there a code on counterfactual impulse responses such as in this paper (section 4) http://www3.nd.edu/~esims1/bachmann_sims_confidence_august.pdf or in Sims and Zha (Macroeconomic Dynamics, 2006)? They construct counterfactual shocks in order to set the reponse of one variable to an ide...

Dear Tom,

Can I plot a series as a line on top of stacked bars when the series are not consistently positive and negative?

Thanks for your help

I think it is now working (see graph). The tightening/easing periods are observed and plotted as shaded areas. The VAR-part seems to add little information as the latent variable mostly reflects the +1/-1 dummies, but at least the code seems to work.

Dear Tom,

Thanks for your prompt response. I am trying to generalize the codes for Dueker's Qual VAR from binary data to three alternative realizations.

Thanks again!

Dear all, I want to draw a latent variable from a truncated normal. Here I repeat the crucial commands. First, I specifiy two policy actions, easing and tightening: set easing= loose ==1.0 set tighhtening= tight ==-1.0 set ystar = %if(tightening,-1.0,%if(easing,1.0,0.0)) The latent variable should b...

Yes, I fully agree. The advantage is that I can discuss the asymmetry in terms of a single vector of asymmetry-dummies, not two vectors.

Thanks,
Peter

Dear Tom, I work with the VAR model with shocks to exogenous variables and want to distinguish positive and negative innovations to the exogenous variable. Currently, I include the change in the interest rate as an exogenous variable and split it into positive and negative ones: system(model=varmode...

Dear Tom,

Are you aware of RATS codes of an asymmetric VAR, i.e. one in which positive shocks and negative shocks could have different effects in absolute terms?

Thanks for your help.
