The Relative standard deviations in dyntable

Stochastic simulations
1

Hi Dynareist!

This is a basic question but sorry I still need to ask.

It is the first time that I use the dyntable (dyntable(options_,‘Relative standard deviations’,).

I got the Relative standard deviations table in the end. Are these REL. S.D. the variables’ volitility or the variables’ volatility relative to the volatility of y sigma(v)/sigma(y)?

VARIABLE REL. S.D.
y 1.5653
C 2.2859
I 2.7815
l 0.6635
tau 1.3503

Really appreciate your help.

That is not a standard Dynare implementation. Where did you get the results from?

Hi jpfeifer,

Thank you for your reply.

These results are obtained from a model I build and ran in Dynare.

I used this code to generate results:

statistic1 = 100*sqrt(diag(oo_.var(1:30,1:30)))./oo_.mean(1:30);
dyntable(options_,‘Relative standard deviations’,{‘VARIABLE’,‘REL. S.D.’},M_.endo_names(1:30,:),statistic1,10,8,4);

I understand that it’s not a user-facing function.

Just confused that are these REL.S.D. results indicating the variables’ volatility relative to the y’s volatility or the variables’ volatility of themselves because I can’t find this function in the manual.

Thank you for your help.

This is not about the function. You input

 100*sqrt(diag(oo_.var(1:30,1:30)))./oo_.mean(1:30)

which is 100 times the standard deviation divided by the mean of the respective variable.
