If const is FALSE, b is set equal to 0 (zero), and the m-values are adjusted so that y = mx. If const is TRUE or omitted, b is calculated normally. Note: If you have a current version of Microsoft 365, then you can input the formula in. TREND returns the y-values along that line for the array of newx's that you specify. It fits a straight line (using the method of least squares) to the array's knowny's and knownx's. If known_x's is omitted, it is assumed to be the array that is the same size as known_y's.Ī logical value specifying whether to force the constant b to equal 0 The TREND function returns values along a linear trend. If more than one variable is used, known_y's must be a vector (that is, a range with a height of one row or a width of one column). If only one variable is used, known_y's and known_x's can be ranges of any shape, as long as they have equal dimensions. The array known_x's can include one or more sets of variables. If the array known_y's is in a single row, then each row of known_x's is interpreted as a separate variable.Īn optional set of x-values that you may already know in the relationship y = mx + b
If the array known_y's is in a single column, then each column of known_x's is interpreted as a separate variable. The set of y-values you already know in the relationship y = mx + b
The TREND function syntax has the following arguments:
