# Compatibility functions (reference)

In Excel 2010 or later, these functions were replaced with new functions that provide improved accuracy and have names that better reflect their usage. You can still use them for compatibility with earlier versions of Excel, but if backward compatibility isn't required, you should start using the new functions instead. For more information about the new functions, see Statistical functions (reference) and Math and trigonometry functions (reference) .

If you're using Excel 2007, you'll find these functions in the Statistical or Math & Trig categories on the Formulas tab.

Function

Description

Returns the beta cumulative distribution function

Returns the inverse of the cumulative distribution function for a specified beta distribution

Returns the individual term binomial distribution probability

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

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

Returns the test for independence

Joins two or more text strings into one string.

Returns the confidence interval for a population mean

Returns covariance, the average of the products of paired deviations

Returns the smallest value for which the cumulative binomial distribution is less than or equal to a criterion value

Returns the exponential distribution

Returns the F probability distribution

Returns the inverse of the F probability distribution

Returns a value along a linear trend

Note: In Excel 2016, this function is replaced with the new Forecasting functions, but it's still available for compatibility with earlier versions.
