Descri\u00e7\u00e3o Geral da Fun\u00e7\u00e3o<\/h2>\n

A fun\u00e7\u00e3o LOGNORM.INV (conhecida como INV.NORMALLOG no Google Planilhas) \u00e9 usada para calcular o inverso da fun\u00e7\u00e3o de distribui\u00e7\u00e3o acumulada log-normal para um valor de probabilidade especificado. A distribui\u00e7\u00e3o log-normal \u00e9 apropriada para modelar valores que s\u00e3o sempre positivos e geralmente t\u00eam distribui\u00e7\u00e3o assim\u00e9trica, sendo amplamente utilizada em campos como economia e engenharia.<\/p>\n

Sintaxe e Exemplos<\/h2>\n

A sintaxe da fun\u00e7\u00e3o \u00e9 a seguinte:<\/p>\n

LOGNORM.INV(probabilidade, m\u00e9dia, desvio_padr\u00e3o)<\/code><\/pre>\n
Os par\u00e2metros s\u00e3o definidos como:<\/p>\n
    \n
  • probabilidade<\/strong>: a probabilidade correspondente \u00e0 distribui\u00e7\u00e3o log-normal inversa, que deve ser um valor entre 0 e 1.<\/li>\n
  • m\u00e9dia<\/strong>: a m\u00e9dia dos logaritmos do conjunto de dados, que deve ser um n\u00famero real.<\/li>\n
  • desvio_padr\u00e3o<\/strong>: o desvio padr\u00e3o dos logaritmos do conjunto de dados, que deve ser um n\u00famero positivo.<\/li>\n<\/ul>\n
    Exemplo no MS Excel:<\/p>\n
    =LOGNORM.INV(0.5, 0, 1)<\/code><\/pre>\n
    Neste caso, a fun\u00e7\u00e3o determinar\u00e1 o valor mediano da distribui\u00e7\u00e3o log-normal, onde a m\u00e9dia do logaritmo \u00e9 0 e o desvio padr\u00e3o \u00e9 1.<\/p>\n
    Exemplo no Google Planilhas:<\/p>\n
    =INV.NORMALLOG(0.5, 0, 1)<\/code><\/pre>\n
    Este comando retorna o mesmo resultado que no MS Excel, demonstrando a compatibilidade das fun\u00e7\u00f5es entre as duas plataformas.<\/p>\n
    Aplica\u00e7\u00f5es Pr\u00e1ticas<\/h2>\n
    An\u00e1lise de Tempo de Espera em Filas<\/h2>\n
    Considerando dados que indicam que o tempo de espera em uma fila \u00e9 distribu\u00eddo log-normalmente com m\u00e9dia logar\u00edtmica de 2 e desvio padr\u00e3o de 1.5, desejamos descobrir o tempo m\u00e1ximo de espera com 90% de certeza.<\/p>\n
    =LOGNORM.INV(0.9, 2, 1.5)<\/code><\/pre>\n
    Esse c\u00e1lculo nos fornece o tempo de espera m\u00e1ximo que n\u00e3o ser\u00e1 excedido em 90% dos casos, assumindo uma distribui\u00e7\u00e3o log-normal.<\/p>\n
    Proje\u00e7\u00e3o de Vendas<\/h2>\n
    Em uma situa\u00e7\u00e3o de proje\u00e7\u00e3o de vendas futuras, onde presume-se que as mesmas seguem uma distribui\u00e7\u00e3o log-normal com m\u00e9dia logar\u00edtmica de 3 e desvio padr\u00e3o de 0.7, podemos determinar um valor de vendas que espera-se exceder em apenas 10% das ocasi\u00f5es:<\/p>\n
    =LOGNORM.INV(0.1, 3, 0.7)<\/code><\/pre>\n
    Esse resultado pode ser usado para estabelecer metas ambiciosas de vendas ou para realizar an\u00e1lises de risco em proje\u00e7\u00f5es financeiras.<\/p>\n\n\n\n\n
