Hi, I removed your other thread because it's a duplicate of this one. Forecasting
is slippery business if you don't know at least a bit about the probability distribution
of your present data. You can order your data timewise and simply use one of the
available predictors, or simply use a Lagrange polynomial to find a value in the (near)
future. If the probability distribution behaves kind of 'calm' you might consider a moving
average function, optionally using weights on the sample data. An exponential function
does quite nice here.

kind regards,

Jos
