distro.spad line 1447

A package to apply polynomial transformations to distributions and integrate polynomials with respect to distributions.

apply: (UPS, Distribution R) -> Distribution S
apply(p, d) computes the distribution of the random variable p(X)$ where X has distribution d.
eval: (Distribution R, UPS) -> S
eval(d, p) evaluates the distribution d as a linear functional on the polynomial p. Same as integrate(p, d).
integrate: (UPS, Distribution R) -> S
integrate(p, d) integrates the polynomial p against the distribution d. Same as eval(d, p).
