Abstract
Implementations of the present disclosure include receiving user input, the user input indicating a distribution type and a correlation factor, providing the distribution type and correlation factor for identifying an approximate correlation representation (ACR) histogram from a plurality of ACR histograms based on the distribution type and the correlation factor, receiving the ACR histogram, retrieving a first distribution associated with a first uncertain value and a second distribution associated with a second uncertain value from computer-readable memory, processing the ACR histogram, the first distribution and the second distribution to generate a correlation histogram that represents a correlation between the first uncertain value and the second uncertain value, and displaying the correlation histogram on a display.
