WhichDist for Excel
de NCU TECHNOLOGY
Guided input analysis in Excel: fit distributions, rank with AICc/AD/KS, and prove it with plots.
WhichDist for Excel turns a selected range into a rigorous input-analysis workflow — without leaving Excel. Characterize your sample, answer a short guided wizard (data nature + engineering discipline), and WhichDist fits candidate probability distributions, ranks them with an AICc-led composite (always showing Anderson–Darling and Kolmogorov–Smirnov), and proves the recommendation with histogram + PDF, ECDF, Q–Q, and top-3 overlay plots.
Built for engineers and technical students. Free analysis runs entirely offline — your sample data never leaves Excel. Results write back to a WhichDist_Results sheet, with Excel and JSON export included.
