Overview
A metric value, with an expected value and a variance; represents a count that may be either exact or estimated (i.e. when sampled).

#value ⇒ Fixnum
The expected value of the metric.
Corresponds to the JSON property value

#variance ⇒ Fixnum
The variance (i.e. square of the standard deviation) of the metric value.
If value is exact, variance is 0.
Can be used to calculate margin of error as a percentage of value, using
the following formula, where Z is the standard constant that depends on the
desired size of the confidence interval (e.g. for 90% confidence interval,
use Z = 1.645):
marginOfError = 100 * Z * sqrt(variance) / value
Corresponds to the JSON property variance
