Abstract: System and method for generating time series forecasts based on probabilistic data are disclosed. A processor receives a request to identify at least one feature of a dataset that is most closely correlated to a single feature specified in the received request. The dataset includes the probabilistic data of the time series. The processor identifies a set of original features within the dataset and derives a degree of dependency between a single specified feature and each original feature by using a temporally first portion of the dataset. After deriving a degree of dependency between all the features including the single specified feature and each engineered feature of the set of original features, the processor identifies an original feature or an engineered feature with the highest degree of dependency as the at least one feature of the dataset that is most closely dependent to the single specified feature.
