### Pull Random Numbers from my Data (Python)

Let's imagine I have a series of numbers that represents cash flows into some account over the past 30 days in some time window. This data is non-normal but it does represent some distribution. I ...

### How can I build a simulation environment that assess different risk policies? [closed]

I work in fin-tech and would like to build some sort of simulation program to assess how different inputs will impact net revenue. For example, if we create new policies based on ML scores, how would ...

### What is the difference between domain randomization and data augmentation?

Domain randomization (https://arxiv.org/abs/1703.06907) is used to create a synthetic dataset with enough variance that it will encompass unseen real data, as just one variation. I am trying to ...

### monte carlo simulation for impact to revenue by adjusting credit limits

I've been tasked with prioritizing projects for the year. One of them is to estimate the impact to net revenue if we were to adjust the purchase limits for our users. Our platform is transactional in ...

### Ways to simulate weather data over several periods (Python or R)?

I have a time series dataset that has several variables for a state/province for fixed periods of time. That is for state A, there are samples from April 2017 to July 2019. Of course, I thought adding ...

### What is the best approach (and why) to identify a conic section given the the points along its cross-section and its vector magnitudes over time?

I have an N-body simulation that calculates the position, velocity, and acceleration of each body at every frame over the course of some duration. As an example, I tested the algorithm using our solar ...
