How to generate random correlation matrix that has approximately normally distributed off-diagonal entries with given standard deviation? Then: G ( y) = P [ Y y] = P [ c X y] = P [ X y c] = F ( y c) Now we differentiate and we get: g ( y) = f ( y c) 1 c. where g is the density function for Y and f is the density function for X. . Normal distribution The normal distribution is the most widely known and used of all distributions. It only takes a minute to sign up. The reason is that if we have X = aU + bV and Y = cU +dV for some independent normal random variables U and V,then Z = s1(aU +bV)+s2(cU +dV)=(as1 +cs2)U +(bs1 +ds2)V. Thus, Z is the sum of the independent normal random variables (as1 + cs2)U and (bs1 +ds2)V, and is therefore normal.A very important property of jointly normal random .
