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 boundmatrix 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.

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 ?

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)

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.

hi
i can`t find this instruction pdf file!!! i extracted factors and i have x and y variables but i don`t know how i have to use them in eviews.
