View source: R/CRV.computeVar.R
Description
Calculul dispersiei unei v.a. continue.
Usage
1
CRV.computeVar(obj)
Arguments
obj
obj -: v.a. continua construita cu ajutorul ContinuousRV::CRV.
Details
Pentru determinarea valoriile variantei se utilieaza formula:
m <- CRV.computeEV(obj)
integrand <- function(x) {
(x - m)**2 * obj@fun(x)
}
result <- integrate(integrand, lower = obj@lo, upper = obj@hi)$value
Examples
1
2
X <- CRV(fun = function(x) {exp(1)**(-x**2/2)})
var <- CRV.computeVar(X)
