teda: teda: An implementation of the Typicality and Eccentricity...

Description Details References


The package provides functions to calculate both the batch and recursive typicality and eccentricity values of given observations.


TEDA provides a non-parametric technique to determine how eccentric/typical an observation is with respect to the other observations generated by the same process. Available as either a batch function working over a whole dataset, or as a recursive one-time-pass function that needs the current mean and variance values to be passed as arguments.

Both batch and recursive methods return a datatype (tedab or tedar) which provide print and summary generic function implementations. The batch object also provides a generic plot function.

Further work will implement more of the analytical framework built up around TEDA, such as clustering algorithms.
