Anomaly Detection API Reference
ChemometricsTools has a few anomaly detection methods. Feel free to read the API below. If that's too abstract, check out the shoot-out example : AnomalyDetection
Functions
ChemometricsTools.Hotelling
— Method.Hotelling(X, pca::PCA; Quantile = 0.05, Variance = 1.0)
Computes the hotelling Tsq and upper control limit cut off of a pca
object using a specified Quantile
and cumulative variance explained Variance
for new or old data X

object.
ChemometricsTools.Q
— Method.Q(X, pca::PCA; Quantile = 0.95, Variance = 1.0)
Computes the Q-statistic and upper control limit cut off of a pca
