Skunks and skunkettes, I got sets of data, to be specific electrical energy consumption against time of the day for various residential units in Nairobi. I have so far presented this in line graphs by use of Ms excel and its required of me to come with mathematical equations for this curves. Any suggestions? _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

Its called Numerical Analysis -a unit in al engineering n science courses- if u have a set of data organized into an [x,y] state, it is possible to come up with equations that define the data char. using forward/backward difference tables. Its the only possible way i knw. For further details contact me offlist. All the best though n God bless u. On 5/31/09, BOOKER OMOLE <bo7omole@hotmail.com> wrote:

Simon just to be more specific, this are called electricity load curve, i intend to come up with a forecasting model that can predict short term power demand. The only way I know is to collect data per house unit, which i have done ,so i have time of the day on my x-axis and power in watts on my y axis. Then try come up with equations to describe this curves. That's where I'm stack.

the last time i used such eqns was in my 2nd yr in campo where we did draw some curves using C++ and java in Numerical analysis and Scientific computing units. Some of the areas or eqns were Runge Kutta,Newton Ralphson,Successive over relaxation n many others....like Eigen vectors and values calculations.....

There's octave on linux which is abit like matlab - only that it is free (but command line based - last time I used it - a while ago). On Tue, Jun 2, 2009 at 3:33 PM, steve moha <steve.moha@gmail.com> wrote:
