I would like to do a stochastic simulation in R to approximate stock and bond returns. I was planning on using historical data of predefined portfolios and have R studio calculate simulate returns let's say in 30 years time. For example if one saves money for retirement and puts it into a portfolio, how much could he have in 30 years.
I am new to R and a little bit lost. Which model would you use? I.e. Monte Carlo? Do I need to be very strong in statistics to do this or merely just need to find the right code, and the software will do it for me?
Thank you a lot for your help!
