> Key: FLINK-2379
> URL: https://issues.apache.org/jira/browse/FLINK-2379
> Project: Flink
> Issue Type: New Feature
> Components: Machine Learning Library
> Reporter: Sachin Goel
> Assignee: Sachin Goel
>
> Design methods to evaluate statistics over dataset of vectors.
> For continuous fields, Minimum, maximum, mean, variance.
> For discrete fields, Class counts, Entropy, Gini Impurity.
> Further statistical measures can also be supported. For example, correlation
> between two series, computing the covariance matrix, etc.
> [These are currently the things Spark supports.]
