![]() 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 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 ![]() ![]() Utilizing the trendline equation can provide valuable insights and identify patterns in the data. 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 trendline equation can be used for making predictions for future data points. Select an appropriate horizontal range of cells, enter the LINEST () formula, the confirm with ctrl-shift-enter (not just enter). The set of y-values you already know in the relationship y = mx + b If I understand correctly, this is usually because you have failed to follow the appropriate 'array formula protocol' for entering an array formula like LINEST (). The TREND function syntax has the following arguments: ![]()
