Experimenting with Diodes and Non-Linear Curve Fitting

How much does a diode's characteristics actually diviate from diode to diode? I measured a small number of diodes, and then recovered the SPICE DC parameters. Due to the limitations of my equipment, I only did this in the DC forward biased region. I'll also describe how to accurately recover the SPICE parameters using numerical methods.
