Pedigree Confidence Intervals and Monte Carlo confusion

Reported by: joeb Owned by: joeb
Priority: normal Milestone: Ecopath 6: release 6.2
Component: Monte Carlo Version:
Severity: feature Keywords:


In the Pedigree interface there is a confidence interval labeled "Conf. interv. (+/-%)" associated with a Pedigree level. The confidence interval is then used to set the CV (coefficient of variation) for the Monte Carlo. The Pedigree interface supplies default values that increase as the data gets more uncertain. The label sort of implies that this is a Confidence Interval which are usually expressed as two number, some percentage of the data is within some interval i.e. 90% of the data is within 5%. If this is intended to be a Confidence Interval then there should a something stating the interval, 95 percentile, 1 standard deviation... Also in this case the defaults are then backwards and should decrease as the data gets more uncertain. If this is some other kind of measure then the label should be changed to remove the confidence interval reference. Possibilities "CV for MonteCarlo" cv=sd/mean, "Uncertainty (+/-%)" others....
