How To Use GAMMAINV() Function in Google Sheets



Common questions about the GAMMAINV formula include:
- What does the GAMMAINV formula do?
- What are the parameters for the GAMMAINV formula?
- How do I apply the GAMMAINV formula?

The GAMMAINV formula computes the inverse of the cumulative distribution function for Gamma. It can be used to calculate the value of “x” when given the probability and the parameters of a Gamma distribution.

The GAMMAINV formula can be correctly typed as: “=GAMMAINV(probability, shape, scale)”.

Common typos of the GAMMAINV formula include: “GAMMAINV”, “GAMMAINV()”, “=GAMMAINV”, or “=GAMMAINV()”.

The GAMMAINV formula can be used inappropriately when the parameters are specified incorrectly, when non-numeric values are entered, or when it is used to calculate the probability of a range instead of a specific value.

Common pitfalls when using the GAMMAINV formula include: forgetting to add quotation marks to parameters that are strings; misremembering the order of the parameters; and assuming that the inputted parameters are valid.

Common mistakes when using the GAMMAINV Formula include: entering parameters that are not valid numbers; mistyping the formula; entering parameters that don’t match the gamma distribution you are trying to evaluate; and confusing gamma and normal distributions.

Common misconceptions people might have with the GAMMAINV Formula include: that GAMMAINV can calculate the probability when given parameters, when in fact it only calculates the value “x” given a probability; that GAMMAINV can be used for distributions other than gamma; and that GAMMAINV is a probability function when it is actually an inverse cumulative distribution function.
