Rolling median algorithm in C
...alue incrementally:
quantile += eta * (sgn(sample - quantile) + 2.0 * p - 1.0)
The value p should be within [0, 1]. This essentially shifts the sgn() function's symmetrical output {-1, 0, 1} to lean toward one side, partitioning the data samples into two unequally-sized bins (fractions p and 1 - ...
