Re: Solver Question



Hello Mario:

Yes, the process I describe was certainly overkill for a simple linear function. I tried that only as a simple example. The context I use it in in the manuscript I described is considerably more challenging. I use it to determine coefficients in a 10th order Fourier Series Approximation. I don't believe that linest would help me much with that.

Since posting this to the gnumeric list, I also posted it to the OpenOffice Calc forum. There I got a response from someone who directed me to a nonlinear solver extension. I have loaded that in to Calc and it works fine.

Thanks,

Jim

Jim,

I think I was able to reproduce the problem: Solver wants constraints. Even
tried adding a dummy constrained variable. Obviously the solver engine
doesn't like that.
Using Solver for this seems an overkill anyway, why don't you try regression
functions: =SLOPE(range of y's, range of x's) and =INTERCEPT(range of y's,
range of x's)

Good luck,

Mario
