Formula Generator - GAMMAINV function
The GAMMAINV function is used to calculate the inverse of the gamma distribution or estimate the shape parameter of a gamma distribution. It takes three arguments: probability, alpha, and beta. The probability is the value at which to evaluate the inverse gamma distribution. The alpha and beta parameters define the shape and scale of the gamma distribution.How to generate an GAMMAINV formula using AI.
To get the GAMMAINV formula, you could ask the AI chatbot something like: "What is the Excel formula for calculating the inverse of the gamma distribution?"
GAMMAINV formula syntax.
The GAMMAINV function in Excel is used to calculate the inverse of the gamma cumulative distribution. It has the following syntax: GAMMAINV(probability, alpha, beta) - probability: This is the probability of the random variable falling below a certain value. - alpha: This is the shape parameter of the gamma distribution. - beta: This is the scale parameter of the gamma distribution. The GAMMAINV function returns the value x such that the cumulative distribution of the gamma distribution with parameters alpha and beta is equal to the given probability.
Calculate the inverse gamma distribution
In this use case, we use the GAMMAINV function to calculate the inverse of the gamma distribution for a given probability, alpha, and beta values.
GAMMAINV(probability, alpha, beta)
Estimate the shape parameter of a gamma distribution
In this use case, we use the GAMMAINV function to estimate the shape parameter (alpha) of a gamma distribution for a given probability, beta, and a known value of the inverse gamma distribution.
GAMMAINV(probability, alpha, beta)
Calculate the time to failure in a reliability analysis
In this use case, we use the GAMMAINV function to calculate the time to failure in a reliability analysis, given the probability of failure, shape parameter (alpha), and scale parameter (beta) of a gamma distribution.
