Re: OrCAD PSpice problem--mote carlo analysis - sigma calcul

First of all, thank wihtewiz's suggestion.
This problem is fixed by myself.

PSpice mote carlo analysis:
mean deviation calculate formula: X= (X1+X2+X3+...+Xn)/n x1...xn is a single case's deviation from nominal value.
Standard sigma calculate formula:
s^2=[(x1-x)^2+(x2-x)^2+......(xn-x)^2]/n
standard sigma is √s^2
So for a single case deviation Xn, the sigma quality is xn/(standard sigma).

If everyone have any question, please contact with me!
In another way, if your chinese is very good. Website: https://hi.baidu.com/rdtech is welcome!
