area under curve and bilinear representation
I've already read tons of materials about this problem...but still can't
fully learn how I can solve my spcific problem. Is there any macro or script that could help me...? I've got a data set X Y and I want to approximate the curve plotted with a bilinear, so that the area under the two curves (non linear and bilinear) is equal... Hope someone help me... thanks in advance |

I hope I'm ot being too simplisitc here -- Do you mean quadratic (2nd order) instead of bilinear? With least squares, you could get y = A x ^2 + B x + C, which would be close. From this you could get the area under the curve. You could adjust C to make the area exactly equal to the area under the non-linear curve. Have you done this on a worksheet (before thinking about a macro)? ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
