In probability theory, calculation of the sum of normally distributed random variables is an instance of the arithmetic of random variables, which can be quite complex based on the probability distributions of the random variables involved and their relationships. This is not to be confused with the sum of normal … See more Let X and Y be independent random variables that are normally distributed (and therefore also jointly so), then their sum is also normally distributed. i.e., if $${\displaystyle X\sim N(\mu _{X},\sigma _{X}^{2})}$$ See more • Propagation of uncertainty • Algebra of random variables • Stable distribution See more In the event that the variables X and Y are jointly normally distributed random variables, then X + Y is still normally distributed (see Multivariate normal distribution) … See more
WebI am calculating the sum of two uniform random variables X and Y, so that the sum is X + Y = Z. Since the two are independent, their densities are f X ( x) = f Y ( x) = 1 if 0 ≤ x ≤ 1 and 0 otherwise. The density of the sum becomes f Z ( z) = ∫ − ∞ ∞ f X ( z − y) f Y ( y) d y = ∫ 0 1 f X ( z − y) d y by convolution. I am stuck at this stage.
