varianceInRange

Compute the range-limited second moment of the distribution.

---

Declaration

 var = varianceInRange(self,zmin,zmax)

Parameters

• zmin lower integration bound
• zmax upper integration bound

Returns

• var range-limited second moment

Discussion

This method evaluates \(\int_{z_{\min}}^{z_{\max}} z^{2} p(z)\,\mathrm{d}z.\) For centered distributions, that integral equals the variance contribution on the interval.
