PROB function

PRO BASIC

The PROB function in Jspreadsheet Formulas Pro is a tool that calculates the likelihood of a specific result based on a set of values and their corresponding probabilities. For instance, if you have a dataset with different outcomes and each outcome has a certain probability attached to it, the PROB function can tell you the probability of a specific outcome occurring. It's a handy function for statistical analysis, predicting trends or making forecasts based on previous data.

Documentation

Returns the probability of an outcome occurring given a range of values and associated probabilities.

Syntax

PROB(range, probability, [lower], [upper])

Parameter	Description
`range`	The range of numeric values to consider for the probability calculation.
`probability`	The probabilities associated with each value in the range argument.
`lower`	Optional. The lower bound of the range of values to consider for the probability calculation. If omitted, defaults to the minimum value in the range argument.
`upper`	Optional. The upper bound of the range of values to consider for the probability calculation. If omitted, defaults to the maximum value in the range argument.

Behavior

The PROB function is used to return the probability that values in a range are between two limits. If the upper limit is not specified, the function will return the probability that values in the range are equal to the lower limit.

If the array or probability array contains logical values or empty cells, those values are ignored.
The function requires that the array and prob_array arguments be of equal size, otherwise, it returns an error.
Both the array and prob_array should contain numeric values. If they contain text, the function will return an error.
The function will return an error if the sum of the probabilities in the prob_array is not equal to 1.
If the lower limit is greater than the upper limit, the function will return 0.

Common Errors

Error	Description
#VALUE!	This error is returned when the array and prob_array arguments are not of equal size.
#NUM!	This error occurs when the lower limit is greater than the upper limit.

Best practices

Ensure that the array and prob_array arguments are of equal size to avoid a #VALUE! error.

Make sure that the sum of the probabilities in the prob_array is equal to 1 to avoid a #N/A error.

Always check that the lower limit is not greater than the upper limit to prevent a #NUM! error.

It's a good practice to make sure the array and prob_array contain numeric values only as text values can lead to errors.

Usage

A few examples using the PROB function.

PROB(A1:A5,B1:B5) returns the probability of any value from A1 to A5 occurring, based on the corresponding probabilities in B1 to B5  
PROB(A1:A5,B1:B5,10,20) returns the probability of any value from A1 to A5 between 10 and 20, based on the corresponding probabilities in B1 to B5
