I need some help on Gaussian distribution. i have two dataset, both are identical and independent distributed, but having mean as 2μ_1 and μ_2, same scenario for the variance. How can I add them?
thank you.

1$\begingroup$ Hey Tonni, welcome to CrossValidated. Your question is unclear. You need to "add distributions"? What do you mean by that? $\endgroup$– GijsCommented Mar 18, 2019 at 10:23

$\begingroup$ hi Gijs, Thank you for your response. I need to add variable X with Y where X and Y are independent and identically distributed with having mean 2μ_1 and μ_2 respectively. In addition, they have variance 2σ_1 and σ_2. How can I add them? $\endgroup$– Tania islamCommented Mar 18, 2019 at 11:30

Create two distributions each with NOB values via monte carlo using the respective mean/variance and simply add them pairwise to create a NOB realizations for the sum. Then compute statistics for the summed set.
