FISHERINV: Excel Formulae Explained

How do you use FISHERINV in Excel?

The FISHERINV function in Excel is a statistical function that calculates the inverse of the F-distribution. The F-distribution is a distribution that is used to calculate the probability of obtaining a certain value or range of values from a sample population. The FISHERINV function in Excel can be used to calculate the inverse of the F-distribution for a given set of values. The function takes two input parameters: the degrees of freedom and the value of the cumulative probability. The function will return the value of the inverse of the F-distribution for the given input parameters.

What is the syntax of FISHERINV in Excel?

The FISHERINV function in Excel calculates the inverse of the F-distribution. The syntax of the FISHERINV function is:

=FISHERINV(alpha,beta,degrees of freedom)

alpha is the alpha level beta is the beta level degrees of freedom is the number of degrees of freedom

What is an example of how to use FISHERINV in Excel?

The FISHERINV function is used in Excel to calculate the inverse of the F-distribution. The function takes three arguments: the first is the degrees of freedom, the second is the probability, and the third is the quantile. The function returns the inverse of the F-distribution for the given values. An example of how to use the FISHERINV function in Excel is shown below:

In the example, the function is used to calculate the inverse of the F-distribution with 10 degrees of freedom and a probability of 0.05. The quantile is also calculated, which is the point at which the inverse of the F-distribution is equal to the given probability. The results of the function are shown in the table below:

The inverse of the F-distribution is equal to 1.966 at the quantile of 0.05.

When should you not use FISHERINV in Excel?

There are several occasions when you should not use FISHERINV in Excel. One is when you have a data set with an even number of data points. In this case, the FISHERINV function will return an incorrect result. Another time you should not use FISHERINV is when you have a data set with zero values. In this case, the FISHERINV function will return the #VALUE! error. Additionally, you should not use FISHERINV when you have a data set with negative values, as this will result in an incorrect answer.

What are some similar formulae to FISHERINV in Excel?

The FISHERINV function is used to calculate the inverse of the Fisher transformation. There are a few other similar formulas that can be used in Excel. The NORMSINV function is used to calculate the inverse of the normal distribution. The TTEST function is used to calculate the t-test. The ZTEST function is used to calculate the z-test.
