Good–Turing frequency estimation is a statistical technique for estimating the probability of encountering an object of a hitherto unseen species, given a set of past observations of objects from different species. In drawing balls from an urn, the 'objects' would be balls and the 'species' would be the distinct colors of the balls (finite but unknown in number). After drawing red balls, black balls and green balls, we would ask what is the probability of drawing a red ball, a black ball, a green ball or one of a previously unseen color.

- Good–Turing推定 (英語: Good–Turing frequency estimation) は、これまでに観測されていない種の対象に遭遇する確率を、異なる種の対象 (有限個だが総数は不明) についての過去の観測情報から推定するための統計的手法である。壺から玉を取り出すことを考えると、「対象」はボールに対応し、「種」は玉の色に対応する。赤色の玉 黒色の玉 緑色の玉 を引いたあとに、次に赤色の玉、黒色の玉、緑色の玉、あるいはこれまでに観測していない色の玉が出る確率はいくつか、というのがここでの問題である。 (ja)
- Estimativa de frequência Good-Turing é uma técnica estatística para prever a probabilidade de ocorrência de objetos pertencentes a um número de espécies desconhecidos, dado observações passadas desses objetos e suas espécies. (Desenhando bolas de uma urna, os "objetos" seriam bolas e as "espécies" seriam as cores distintas das bolas (finitas mas desconhecidas em número). Depois de desenhar bolas vermelhas, bolas pretas e bolas verdes, nós perguntaríamos qual é a probabilidade de desenhar a bola vermelha, a bola preta, a bola verde ou uma de uma cor ainda nao vista.)
