thank you , Dakila !!i am grateful ! we are lucky to be able to benefit from your help !


i followed your instructions and i obtain the impulse response matrix(for shock egal to -0.25) , i use the option graph and i obtain the graphs of impulse response without confidence intervals , the axis 0 and the name of the selected variables (see workfile). what should i do to get them (like figure 01 in your exple) ?

for the conditional forecast,you tell me i should transform for exple series2 to the non standardized on . i must do it :
-before i estimate eq01 ?
- before i forecast the factors ?
- before i forecast series2 ?

i transform only the selected variable (series2) , NOT the series contrained (ffr). true ?

THANK YOU very much !

You should do the same things for the confidence interval. For example:

Code: Select all

matrix irf_ub=irfxmat_ub01/irfxmat_ub01(1,1)
irf_ub = irf_ub*(-0.25/ffr_std) ' upper bound
matrix irf_lb=irfxmat_lb01/irfxmat_lb01(1,1)
irf_lb = irf_lb*(-0.25/ffr_std) ' lower bound

Easiest way to draw the figure is copy the matrix to excel then draw the graph.

for the conditional forecast,you tell me i should transform for exple series2 to the non standardized on . i must do it :
-before i estimate eq01 ?
- before i forecast the factors ?
- before i forecast series2 ?

After the conditional forecast you should transform for expel series2
i transform only the selected variable (series2) , NOT the series contrained (ffr). true ?

Yes that is true.

Thank you for your answer, Dakila !
i obtain the ifr with confidence interval.


i transform some of my variables to induce stationarity .when i perform 'the conditional forecast ',i have for exple the conditional forecast of the
dlog pib ( i transform this variable back to the non-standardized one).

i would like to obtain the conditional forecast of the real value (without transformation ). in general ,i can applied the formula
Tx+1 = Tx *e(dlogpib) . how can i traduce this formula to employ it in eviews ?

thank you in advance !!

hi Dakila !

can you add the transformation' second difference of log ' and 'first difference' please ? i have no stationary variables with dlog so i must use ddlog.



Thank you very much !!

Hi Dakila,

could you add the others possible transformations ? ( the fist difference ,the second difference and ddlog)


Thanks you very much for your answer !!

Hi,

The impulses responses of the variables to an unexpected increase in ffr are to be interpreted in "pourcentage points " in the model ? for exple, changes in GDP are expressed in pourcentage point ? or in standard deviation ?



Thanks

Note that the figures report impulse responses in standard deviation units.
