TREND function

The TREND function is one of the statistical functions. It is used to calculate a linear trend line and returns values along it using the method of least squares.

Syntax

TREND(known_y’s, [known_x’s], [new_x’s], [const])

The TREND function has the following arguments:

Argument	Description
known_y’s	The set of y-values you already know in the y = mx + b equation.
known_x’s	The optional set of x-values you might know in the y = mx + b equation.
new_x’s	The optional set of x-values you want y-values to be returned to.
const	An optional argument. It is a TRUE or FALSE value where TRUE or lack of the argument forces b to be calculated normally and FALSE sets b to 0 in the y = mx + b equation and m-values correspond with the y = mx equation.
