WEIBULL.DIST

Formulas / WEIBULL.DIST
Calculate the Weibull distribution.
==WEIBULL.DIST(x,a,b)
  • x - required
  • alpha - required
  • beta - required
  • cumulative - required

Examples

  • =WEIBULL.DIST(A2,A3,A4,TRUE)

    Using the WEIBULL.DIST function, you can calculate the Weibull cumulative distribution function for a set of terms. This example calculates the Weibull cumulative distribution function for the terms in column A, column B, and column C.

  • =WEIBULL.DIST(A2,A3,A4,FALSE)

    You can also calculate the Weibull probability density function for a set of terms using the WEIBULL.DIST function. This example calculates the Weibull probability density function for the terms in column A, column B, and column C.


Summary

The WEIBULL.DIST function calculates the Weibull distribution, which is commonly used in reliability analysis.

  • The WEIBULL.DIST function is used in reliability analysis to calculate the Weibull distribution.
  • The function requires three arguments: the value to evaluate, and two parameters to the distribution.

Frequently Asked Questions

What is the WEIBULL.DIST function?
The WEIBULL.DIST function is a statistical function that returns the Weibull distribution. The Weibull distribution is used in reliability analysis.
What are the parameters of the WEIBULL.DIST function?
The parameters of the WEIBULL.DIST function are the x-value, which is the value at which the distribution is to be evaluated, the shape parameter, which is the shape of the distribution, the scale parameter, which is the scale of the distribution, and the cumulative flag, which determines whether the cumulative probability is returned or not.
What is the shape parameter in the WEIBULL.DIST function?
The shape parameter is a value that determines the shape of the Weibull distribution. It controls how quickly the data converges to the mean.
What is the scale parameter in the WEIBULL.DIST function?
The scale parameter is a value that determines the scale of the Weibull distribution. It affects the overall spread of the data.
What is the cumulative flag in the WEIBULL.DIST function?
The cumulative flag is a boolean value that determines whether the cumulative probability is returned or not. If the cumulative flag is set to TRUE, the cumulative probability is returned. If the cumulative flag is set to FALSE, the probability density is returned.
What is reliability analysis?
Reliability analysis is a statistical method used to estimate the probability of a system or component failing. It uses data on the system's performance over time to make predictions about future performance.
