standardDeviation
Element : standardDeviation
PQ 0...1 The primary measure of variance/uncertainty of the value (the square root of the sum of the squares of the differences between all data points and the mean). The standard deviation is used to normalize the data for computing the distribution function. Applications that cannot deal with probability distributions can still get an idea about the confidence level by looking at the standard deviation.
distributionType
Attribute : distributionType
ProbabilityDistributionType 0...1 A code specifying the type of probability distribution. Possible values are as shown in the attached table. The NULL value (unknown) for the type code indicates that the probability distribution type is unknown. In that case, the standard deviation has the meaning of an informal guess.

There are no specific rules for this element.
