captest.filters.AbsDiffPrev

class captest.filters.AbsDiffPrev(*, column, threshold, custom_name, name)

Remove intervals with a large fractional change from the previous interval (a step-change / stability filter).

For column c the test is abs(c.diff() / c) <= threshold; intervals above the threshold are removed. column defaults to the regression POA column when None. The first interval has an undefined difference (NaN) and is removed, matching the original filter_abs_perc_diff_prev_interval.
