Hi @Singh basne,

I hope you've already had a chance to go through the Bear Toolbox documentation. I recommend taking a look at Chapter 4 (page 45 onwards), which provides steps for implementing shock-specific methodologies.

Bear Toolbox User Guide: https://github.com/european-central-bank/BEAR-toolbox/blob/master/tbx/doc/BEAR_User_guide_v5.pdf

You can also explore the existing implementations of "impulse response functions" within the Bear Toolbox which are compatible with different model types. If you need to adjust for a specific shock size, modify the "initial shock" according to the data you have.

Hope this is beneficial and gives a good starting point for your tasks.
