O QUE SIGNIFICA GAMMA DISTRIBUTION EM INGLÊS
Distribuição Gamma
Na teoria da probabilidade e nas estatísticas, a distribuição da gama é uma família de dois parâmetros de distribuição de probabilidade contínua. A distribuição exponencial comum e a distribuição do qui-quadrado são casos especiais da distribuição gama. Existem três parametrizações diferentes em uso comum: ▪ Com um parâmetro de forma k e um parâmetro de escala θ. ▪ Com um parâmetro de forma α = k e um parâmetro de escala inversa β = 1 / θ, chamado de parâmetro de taxa. ▪ Com um parâmetro de forma k e um parâmetro médio μ = k / β. Em cada uma dessas três formas, ambos os parâmetros são números reais positivos. A parametrização com k e θ parece ser mais comum na econometria e em certos outros campos aplicados, onde e. A distribuição gama é freqüentemente usada para modelar tempos de espera. Por exemplo, no teste de vida, o tempo de espera até a morte é uma variável aleatória freqüentemente modelada com uma distribuição de gama.
definição de gamma distribution no dicionário inglês
A definição de distribuição de gama no dicionário é uma distribuição contínua de dois parâmetros a partir da qual derivam as distribuições de qui-quadrado e exponencial, Gamma escrita, onde α e β são maiores do que zero e definidos em termos da função gama.
