Abbreviation: StndNormPoint
Category: Statistical
Input Parameters:
| Name | Range | Default |
| Time Series | ||
| Periods | Int >= 2 | 10 |
| Z-Score | Real | 1.5 |
Calculation:
mean(X) + Z-Score * StndDev(X,n)
where
mean(X) = mean average of X over the last n periods
X = Time Series
n = Periods
StndDev represents Standard Deviation
Discussion:
Provides a data value relative to a time series mean and standard deviation. A Z-score of one returns the mean plus one standard deviation, while a Z-score of two returns the mean plus two standard deviations. Likewise, a Z-score of negative one returns the mean minus one standard deviation, while a Z-score of negative two returns the mean minus two standard deviations.
