diode series resistance

I got a homework question which says

Using PSpice simulator, design the following circuits and calculate diode parameters:

"For diode evaluation models (a) D1N4002 and (b) D1N914, find built-in series
and shunt resistors. Use excel and empirical diode equation to simulate D1N4002 I-V curve (no additional series Rs and shunt Rsh resistors); by fitting the data, find diode ideal factor."

I got the IV graph but i am not able to understand whats the procedure to find the series resistance of the diode. i mean is it at specific point along the curve.
