I have a sets of data that I have to find the proper parameter for fitting this data to an arc tangent curve. For example if I am monitoring the price of several products during the lifetime of this product, each product can be mapped in an arc tangent curve (price -> date).
In Excel i can go that using Solver and it will provide me with 4 parameters that defines my arc tangent curve (inflection , slope,Range and Shift)

Is there any way that I can do that in SQL2008?
Thanks,

edit: moved to proper forum
