μ, a (a := |a|) Mean and half-width of distribution. •
lgN, .seed (Sugg., lgN ≲ 6) No. (log10) of trials, random no. gener. seed. •
klass No. of histo. classes. •
Show values Shows the coordinates of the graph. •

Simulates, via Monte Carlo (limited time), data from a "raised" cosine pdf.  Its formulas, with β = (xμ)⁄a, are f(x) = (1⁄a).cos²[(π⁄2) β] (inflection points at μ ± a ⁄ 2), and F(x) = ½ [1 + β + (1⁄π) sin(π β)]. Solving this equation (given random F) for β requires a numerical method, relatively slow, as (used) bisection, or of uncertain convergence, as Newton-Raphson.

Plots the density function (pdf), f(x), the simulated curve, and the probability function (cdf), F(x).
