Hi Lisa,

It is not clear to me what you mean by z-normalizing a time series.
Would you clarify how that should be done? Perhaps that means
scaling to a constant standard deviation?

And similarly, how would one scale betas to z-scores? Do you
mean applying the Fisher z-transform to R values? If so, that is
fairly simple. But R values are generally not called betas, so I
suspect you have something else in mind.
