The TREND function has the syntax TREND(known_y's,known_x's,new_x's,const).
In order to output the array of estimated y values on a spreadsheet, the
Excel Help entry specifies that a range must be selected beginning with the
cell in which the TREND function is entered and extending downward so that
the number of cells in the range is equal to the number of estimated y
values. The user is then instructed to press F2, and then press
CTRL+SHIFT+ENTER, causing the estimated y values to populate the selected
range. That method works fine for outputting the estimated y values on a
spreadsheet, but how do I output the estimated y values as an array within a
VBA subprogram?
