# KNIME Nodes

# Data Generation with Flow Variables

It is typical for most Market Simulation workflows to generate input data in a single pass.

While the Matrix Distributions node can only generate *correlated* Normal Distributions, the Customer Distributions node can generate many different, albeit *uncorrelated*, Distributions. Both nodes can simultaneously generate many columns of data, and both can be directly used as the Input Willingness To Pay (WTP) Matrix.

But even more complicated and exotic Customer Distributions can be generated using a KNIME Loop and Flow Variables.

In this workflow, seven (7) Sub-Distributions are defined in a list. Each of these Sub-Distributions is then generated, one-by-one, in a loop. Finally, all Sub-Distributions are concatenated vertically in a column as a single Customer Distribution.

*This KNIME Node Use Case provides an example of a useful KNIME workflow. These workflows do not depend upon Market Simulation but can supplement a Market Simulation workflow. If you have not yet installed KNIME, go to Getting Started.*

# Exotic Distribution

This workflow demonstrates how complicated and exotic Customer Distributions can be generated with a Loop and Flow Variables. Here, seven (7) Sub-Distributions are defined in a list and then generated one-by-one in a loop. Each Sub-Distribution is then concatenated together into a single Customer Distribution.
