Correlated Random Variates
Can anybody provide me with a procedure to generate
correlated random variates? How many sets? If only two, then you can use this formula: CRV2 = corr * RV1+ RV2 * (1 - corr ^ 2) ^ 0.5 If you want more than 2, it gets progressively more complicated. I'd suggest an Internet search or try www.riskchat.com, where somebody offered a VBA routine. HTH, Merjet |

Correlated Random Variates
here is a good link:
http://www.kellogg.nwu.edu/faculty/m...ddins.htm#simt See CORAND(CorrelArray, RandSource), entered as an array formula in a range of cells in a row, returns RANDom values for making random variables that have correlations as in the given CorrelArray. (See also NORMIZE.) Also, if U and V are independent std normal then: X=a + bU Y=c + d*rho*U+d*sqrt(1-rho^2)*V are bivariate normal. boyd "Paul Goldwater" wrote in message ...
