How to interpret the output
Fits a nondecreasing sequence by equal-weight least squares using adjacent-block pooling. Input order is preserved. This tool supports equal weights only and supplies no confidence intervals. The monotonicity constraint needs scientific justification. Source checked 14 November 2026.
