Extracting Constant from Non-linear Trend line
Hi, I just want to ask for assistance on how to calculate the constant values on a given trend line (Non-linear). Basicaly standard equation is Y = AX^2 + BX + C. How can I calculate A, B, C, from a given x's_arrays and y's_arrays using excel (without the help from graph trendline). Thank you.:) Tom -- tomsan82 ------------------------------------------------------------------------ tomsan82's Profile: http://www.excelforum.com/member.php...o&userid=35480 View this thread: http://www.excelforum.com/showthread...hreadid=552542 |
