* stats1: add rank accumulator (#383) Adds `mlr stats1 -a rank` for standard competition ranking (1,2,2,4,...) on pre-sorted data, most useful with -s for a rank on every record. * stats1: make rank order-independent by default, add --rank-sorted opt-in fast path The rank accumulator previously only compared each value to the immediately preceding record, silently giving wrong ranks for non-adjacent duplicates (e.g. unsorted input, or interleaved -g groups). Default to correctly computing standard competition rank from all values seen so far (order-independent, buffers values, same approach as percentile accumulators). Add --rank-sorted for callers who can promise sorted input and want the previous O(1)-space streaming behavior instead. * Revert "stats1: make rank order-independent by default, add --rank-sorted opt-in fast path" This reverts commit |
