Machine learning, probability, statistics, prospect theory, game theory, etc., there are various mathematical models in the world.

Some of them are introduced in plain books, and when you read them, you might think "Hoo!"

But I can't use it very much.
Sometimes I forget it, and sometimes it is troublesome to do the calculations in the book myself.

This app saves a little bit of time.

From the mathematical models listed in various books, the following are taken out and made into an application, which makes it easy to simulate.

1. Secretary problem
2. The concept of test deviation
3.DA algorithm for matching
4.Generation of income deviation from income distribution in the Basic Survey on National Life
5. Motivation simulation using hyperbolic discount
6. Simulation of profitability by discount using the value function of prospect theory

What you can find out from this simulation result depends on the people who use it.
