How to use this tool
- Enter the displayed example values,or choose the local input files requested by the controls. Optional source files take precedence where labelled.
- Choose Calculate result and inspect the complete result and any reported limitations.
- Use Download result and each companion download link to save complete outputs. Reset clears output and restores example controls.
Examples
[Value, weight] pairs: [[1,1],[2,2],[5,1]]
Quantile probabilities: [0,0.25,0.5,0.75,1]
Limitations
- Compute weighted empirical inverted-CDF quantiles using exact decimal comparisons. Select the first positive-weight value whose cumulative weight is at least p times total weight;p=0 selects the minimum positive-weight value. Zero weights are ignored; equal values retain source order. No interpolation. Enter1–1000 [value,weight] pairs and1–100 probabilities in[0,1]. Values are JSON decimal numbers; each token has at most100 coefficient digits,128 characters and exponent magnitude1000. Nonnegative weights need positive total. Exact intermediate arithmetic is bounded to4096 digits; exact fractions and original numeric tokens are retained. Download the complete JSON report. All processing stays in your browser. Combined input limit: 400,000 UTF-8 bytes, 100,000 characters per field; report limit: 4 MiB.
- Complete outputs only. Unsupported or oversized input is refused. Follow the displayed job-specific bounds and format policies.
