Frequently Asked Questions

It returns a value from the window that corresponds to the requested percentile using the nearest-rank rule, so the output is always an actual observed level in the sample (after na handling).

Nearest rank snaps to an order statistic; linear interpolation can return values between two sorted observations. Nearest rank is stepwise; interpolation is smoother.

Use nearest rank when you want band levels tied to real prints in the window; use linear interpolation when you want smoother, more continuous percentile estimates.
