ZDISCORDS function detects discords in a standardized (
STANDARDIZE Geo Time Series™. The discord detection
algorithm is based on identifying outlier patterns in the Geo Time Series™. Outliers are patterns which differ significantly from their nearest neighbor.
The following constraints are enforced:
- pattern length must divide window size
- quantization scale must be a power of two from 2 to 65536
ZDISCORDScan only be applied to numeric Geo Time Series™ which are bucketized and filled (i.e. no bucket with missing values).
