I am trying to use a variety of random functions for continuous plots. I find that many exist in JSL, but many do not. Am I missing something here? If you look below you will see in blue the expressions that exist, while those in black do not and I list the variables that I would expect them to take.
random normal(mu, sigma);
random log normal(mu, sigma);
random weibull(beta, alpha);//flipflopped ==> alpha, beta
random weibull threshold;//alpha, beta, theta
random extreme vaule();//lamda, delta
random exponential ();//sigma
random gamma(lamda, scale);//not enough variables
ramdom beta ();//alpha, beta, theta, sigma
random normal mixture([meanvec],[sdvec],[probvec]);
Thanks MS. I totally just mistyped the Beta one. For the others that makes sense.
Do you know with the LEV how that correlates to the Lambda and Delta values that come from JMP distribution analysis? JSL asks for random LEV(mu, signma)
I tried running them as just the mu and sigma that JSL requests, but that does not work. I cannot find any connections online, but I do not know these statistics themselves that well.
For Gamma, a 500,000 point simulation suggests that the lambda that JSL asks for random gamma(lamda, scale)is the alpha from the estimate and the scale is the scale/sigma, but can anyone definitively confirm? I assume threshold is just a shift at the end (e.g +0 for the example below).
Why does JMP sometimes use the same letters and/or names, but others times not. Lambda vs alpha, scale and scale, scale vs sigma.
