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. 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 this is an array formula.you have to highlight the cells equal to the number of items in data type the TREND formula and hit control shift enter. 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). I was a student of statistics in my college, that is ages back before advent of computer and microsoft excel in excel worksheetfunction TREND gives the estimated values of Y(your data). 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:
