Dear All I would like to get the histogram for the following model with discrete and continuous random variables: * with probability 1/3, a random number is drawn from the continuous uniform distribution (min=0, max=1); * with probability 2/3, a random number is drawn from a different continuous uniform distribution (min=-1/2, max=1/2). Any help would be most welcome. Thanks in advance, Paul
