No misspelling variants are generated for Neyman-Pearson lemma in our index, suggesting the orthography follows predictable English patterns. It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.

Etymologically, the entry records: Named after Jerzy Neyman and Egon Pearson. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Neyman-Pearson lemma, spelled N-E-Y-M-A-N---P-E-A-R-S-O-N- -L-E-M-M-A, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
