Evbayiro-IRR Benchmark Dataset for Capital Budgeting Algorithm Comparison

Benchmark dataset for comparing Evbayiro-IRR 0.1.1 with standard capital-budgeting IRR engines and root-finding methods. Version 2.0.0 archives the SEC/Damodaran all-available benchmark evidence used for decision-mismatch analysis. The dataset contains 88,556 public-company rolling-window cash-flow proxy cases, 1,411 companies, 55 Damodaran industries, 11 sectors, 56,795 conventional one-sign-change cases, 31,761 non-conventional multi-sign-change cases, and 962,217 method-result rows. The benchmark compares Evbayiro-IRR with an Excel-style default-guess proxy, Newton-Raphson, secant, numpy_financial.irr, PyXIRR, and a known-bracket bisection control. Required-rate-of-return inputs are sourced Damodaran industry WACC proxies. SEC cases are public-company accounting proxy sequences, not disclosed internal capital-budgeting project files. The archive includes inputs, full method-result outputs, summary tables, paper-ready figures, interpretation catalogs, and regeneration scripts.
