CRV.computeMargDen: CRV.computeMargDen

In AlecuMihai/ContinuousRV: Create and Manipulate Continue Random Variables

Description

Determina densitatile marginale si conditionate a doua variable aleatoare continue (ContinuousRV::CRV) folosindu-se de densitatea comuna a acestora;

Usage

CRV.computeMargDen(X, Y, commonDensity)

Arguments

X	v.a. continua
Y	v.a. continua
commonDensity	Densitatea comuna a celor doua v.a. continue (functie de doua argumente).

Details

Functia printeaza densitatile marginale & conditionate corespunzatoare fiecarei v.a. ;

Note

Functia utilizeaza Ryacas pentru utilizarea calculului simbolic. "Ryacas is an R interface to the free yacas Computer Algebra System. Ryacas allows one to send R expressions, unprocessed yacas strings and certain other R objects to yacas process from R and get back the result. It also has facilities for manipulating yacas strings and R expressions destined for yacas processing.

It can be used for exact arithmetic, symbolic math, ASCII pretty printing and translating R to TeX."

Examples

X <- CRV(fun = function(x){(2197/5412) * (x**2 + 3*x + 1)}, lo = 0, hi = 12/13)
Y <- CRV(fun = function(x) {20000/7708481 * (2 * x**3 - 2)}, lo = 1, hi = 53/10)
com <- function(x, y) {
  x + y
}

CRV.computeMargDen(X, Y, com)
