As far as i know there are three types of outliers:

- innovation outliers

- observation outliers

- structrual outliers

but i do not know what are differences between these three types exactly.

suppose the system model is:

zk= Hkxk+ek

xk=Fk-1xk-1+wk-1

i would appreciate if explain each of them and their differences using above model.

Type 1: Global Outliers (also called “Point Anomalies”)

Type 2: Contextual (Conditional) Outliers

Type 3: Collective Outliers:
