How to count the direct trading data in the gravitational Rubik's Cube?
The direct trading data in the gravitational Rubik's Cube is based on the statistics of input-output ratio. The principle of direct transaction data in the statistics of gravity Rubik's cube of input-output ratio. It uses probability theory to establish a mathematical model, collects the data of the observed system, makes quantitative analysis and summary, and then makes inference and prediction, providing basis and reference for relevant decision-making.
