This topic explains how the Distribution Function operation works
We support the following distributions:
Each distribution connector takes in two parameters,
function parameter, you can select
"CDF" to use the cumulative density function,
"PDF" to use the probability density function, or
"PPF" to use the percentile point function. You can also select
"SF" for the survival function, which is 1 minus the CDF.
value parameter determines the value at which to call the selected function. If
"PPF" is selected, the value must be between 0.0 and 1.0.
The distribution parameters - like μ and σ for Normal Distribution - enter as time series inputs. These will often be provided as outputs of the NGBoost model connector. Our supported distributions use a location and scale parameter (for Normal distribution, μ is the location parameter, and σ is the scale parameter).
See our Create a Price Forecast with Probabilistic Prediction tutorial for examples using the
LaplaceDistribution operation connector.
