CHIINV function

PRO

The CHIINV function in Jspreadsheet Formulas Pro is a statistical function that computes the inverse of the chi-squared distribution. This function is typically used in hypothesis testing or confidence interval estimation. Essentially, it gives you the chi-squared distribution value for a given one-tailed probability and degrees of freedom. This can be very useful in testing the statistical significance of an observation.

Documentation

Returns the inverse of the one-tailed probability of the chi-squared distribution.

Syntax

CHIINV(probability, degrees_freedom)

Parameter	Description
`probability`	A probability associated with the chi-squared distribution.
`degrees_freedom`	The number of degrees of freedom of the distribution. Must be a positive integer.

Behavior

returns the chi-squared critical value such that the area to the right of that value equals the specified one-tailed probability.. Here's how it handles various input types:

Empty Cells: The 'CHIINV' function treats empty cells as zeros.
Text: Any cell with text input will be considered an error.
Booleans: Boolean values are treated as integers 1 (for TRUE) and 0 (for FALSE).
Errors: If either of the arguments are error values, the function will return an error.

Common Errors

Error	Description
#VALUE!	This error occurs when either of the arguments are non-numeric.
#NUM!	Returned when `probability` is ≤ 0 or ≥ 1, or when `degrees_freedom` is < 1 or not an integer.
#DIV/0!	This error is returned when the degrees of freedom is 0.

Best Practices

Always ensure that the supplied probability argument is between 0 and 1. Any value outside this range will result in an error.

The degrees of freedom should be a positive integer. Non-integer or negative values will cause the function to return an error.

Avoid using text or boolean values as input for the 'CHIINV' function to prevent any errors.

Always check your data to ensure there are no empty cells as 'CHIINV' treats them as zeros.

Usage

A few examples using the CHIINV function.

CHIINV(0.05, 3) returns 7.8147
CHIINV(0.01, 6) returns 16.8118
