Keith, I doubt that you want to use Fit each time you wish to evaluate for a specific x. So define a function using Fit and then you can use that function each time you want to evaluate. data = Table[{x, 3 + 5x + Random[Real, {-0.2, 0.2}]}, {x, 0, 10, 0.5}]; f[x_] = Fit[data, {1, x}, x] 3.00155 + 4.99817 x f[8.1] 43.4867 David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ > -----Original Message----- > From: owenzooey at my-deja.com [mailto:owenzooey at my-deja.com] To: mathgroup at smc.vnet.net > I've used > > Fit[data,{1,x},x] > > to determine a best-fit line. > > How can I automatically send the output of Fit to be evaluated using > different values of x? > > Thanks, > Keith N.
