The standard deviation of the Current
in the economy. Don't know how meaningful it is at the moment, but seems to be a way of getting a handle on how equally the stuff is distributed throughout the economy. The higher this is, the more uneven the distribution.
NB : You can't compare sDevs of different economy's with different parameters (eg. noRuns, noSteps, noAgents etc.) as these will have an effect on the sDev.
Is this right? Can someone suggest a better way of measuring the equality of distribution?
