OSR precision

Dear All,

I am computing optimal simple rules using OSR routine.

To check the working of the routine, I tried different sized shocks, e.g., multiplying standard deviations of all! shocks by, e.g., 100.

This seems to not change results in some cases, but in some other cases I obtain different coefficients for the optimal rule.

Q: Is increasing standard deviations of shocks a good way to increasing the precision of the optimizer underlying OSR?

Many thanks for your support!

If the precision is too low, directly change it in osr1.m In line 51 of osr1.m you will find:

Currently, it is hardcoded and you have to change it manually.
