1Blurb::Select the standardized random variables (and associated basis polynomials) from the Askey family that best match the user-specified random variables. 2 3Description::The Askey option employs standard normal, standard 4uniform, standard exponential, standard beta, and standard gamma 5random variables in a transformed probability space. These selections 6correspond to Hermite, Legendre, Laguerre, Jacobi, and generalized 7Laguerre orthogonal polynomials, respectively. 8 9Specific mappings for the basis polynomials are based on a closest 10match criterion, and include Hermite for normal (optimal) as well as 11bounded normal, lognormal, bounded lognormal, gumbel, frechet, and 12weibull (sub-optimal); Legendre for uniform (optimal) as well as 13loguniform, triangular, and bin-based histogram (sub-optimal); 14Laguerre for exponential (optimal); Jacobi for beta (optimal); and 15generalized Laguerre for gamma (optimal). 16 17Topics:: 18Examples:: 19Theory:: 20Faq:: 21See_Also:: method-polynomial_chaos, method-polynomial_chaos-wiener 22
