confidence band in impulse response function

[nesreen]

Hi All,

I am using Eviews 8 to estimate a Var Model, in impulse response graph, Does the two dashed lines in each panel represent 95% confidence band or 90%? and how can i know that?

would really appreciate a prompt response,

Thank you

As stated at the top of the graph, it represents +- 2 Standard Errors.

sorry for the disturbance again, my question is whether this +- 2 band is interpreted as 90 or 95% confidence level? since some papers write 90 while others write 95.. so how can I know that and how can I change it from 90 to 95 and vice versa? Thank you

It is neither. It is +- 2SEs.
