Returns the probability of getting less than or equal to a particular value in a weibull distribution. |
x | The numeric value at which to evaluate the function. |
alpha | The first parameter. |
beta | The second parameter. |
cumulative | The type of function to use True = cumulative probability function False = probability mass function |
Remarks |
* WEIBULL.DIST was added in Excel 2010 to replace this function. * The Weibull distribution is a continuous distribution. * If "x", is nonnumeric, then #VALUE! is returned. * If "x" < 0, then #NUM! is returned. * If "x" = 0, then ?? * If "alpha" = 0, then #NUM! is returned. * If "alpha" is nonnumeric, then #VALUE! is returned. * If "beta" = 0, then #NUM! is returned. * If "beta" is nonnumeric, then #VALUE! is returned. * This function can be used in reliability analysis, such as calculating a device's mean time to failure. * For the Microsoft documentation refer to support.office.com |
