Assume I have three industry datasets: interest rates, inflation and unemployment. Data contains information of last ten years and it's monthly.
Now, I would like to create N possible scenarios of the next year, also monthly.
The idea is to run a Monte Carlo simulation that calculates a function that has interest rates, inflation and unemployment as input parameters. So I would like to create possible scenarios, but since there's a relationship between the parameters I cannot randomly select values. Is there a method to generate random data of multiple parameters taking into account that they are related?
