Error Statistics

qqStats(x, q1, q9)

`x`	Numeric, observation values
`q1`, `q9`	Numeric, quantiles 0.1 and 0.9

qqStats provides several measures of the accuracy of the confidence interval:

difSUM, the amplitude of the confidence interval, its area, normalized respect to the area of the observations.
difMED, the median of all the amplitudes of the confidence interval normalized respect to the maximum amplitude.
uq1NUM, number of events when the observed value is smaller than the quantile 0.1.
uq9NUM, number of events when the observed value is larger than the quantile 0.9
uq1MED, median of the differences between the quantile 0.1 and the observation when the observed value is below the quantile. The differences are normalized with the observation value.
uq9MED, median of the differences between the quantile 0.9 and the observation when the observed value is above the quantile. The differences are normalized with the observation value.
