I've been trying to implement the iman-conover method in python so I could generate correlated random numbers from distributions other than normal (I use a normal & uniform in my example below). ... To use the Iman-Conover transformation, you must specify two things: A set of data and a target correlation matrix. The transformation will induce the specified correlation in the data by rearranging (or permuting) the columns of the data. In other words, the algorithm permutes the columns independentlyto … Zobacz więcej The Iman-Conover transformation is actually a sequence of transformations of multivariate data. The following program defines the Iman-Conover transformation as a SAS/IML … Zobacz więcej The Iman-Conover transformation is a remarkable algorithm that induces a specified correlation structure on a data matrix while preserving the marginal distributions. … Zobacz więcej The following SAS/IML program shows how to use the Iman-Conover transformation to simulate correlated data.
