LOGEST function - Zoho Sheet - Help Guide

LOGEST

Returns an array of statistics for an exponential curve that best fits the given data set.

 

Syntax

 

LOGEST(y_values; [x_values]; [allow_const]; [stats])

y_values: The array or range containing the known (or dependent) y values. E.g. A2:A6

x_values: The array or range containing the known (or independent) x values. It can have more than one variable. It must be of the same size as that of y_values. Defaults to {1,2,3...} if omitted. E.g. B2:B6

allow_const: Logical value that determines whether to return the y-intercept values or not. Defaults to 1 if omitted.

TRUE or 1  - returns the y-intercept values

FALSE or 0 - returns the y-intercept as 1

stats: Logical value that determines whether to return additional regression statistics or not. Defaults to 1 if omitted.

TRUE or 1  - returns the additional regression data

FALSE or 0 - ignores the additional regression data

df

The degrees of freedom from the variance analysis.

ssreg

The regression sum of squares.

Possible Errors

 

Errors

Meaning

#N/A!

  • The function could not find the value it was asked to look for. Commonly occurs in VLOOKUP and similar functions.

#NAME!

  • The function name is incorrect or invalid.

  • The given defined name (if any) is invalid.

  • There is a typo in the defined name used in the function.

  • Double quotes are missing for text values in the function.

  • Colon missing in a cell range reference.

#VALUE!

  • The given argument's data type is incorrect or invalid.
    For example, the function =DATE(A1:A3) will return a #VALUE error when a text value is present in the range.

#REF!

  • The given cell reference is incorrect or invalid. This error may occur when a cell/range has been deleted, moved, or pasted over.
