dMX: Evaluate the d (pdf) and p (cdf) functions from GAMLSS...

In gamlss.mx: A GAMLSS add on package for fitting mixture distributions

Description

The functions dMX and pMX can be used to evalaluate the pdf (p function) and the cdf (p function) repectively from a gamlss.family mixture.

Usage

dMX(y, mu = list(mu1 = 1, mu2 = 5), sigma = list(sigma1 = 1, sigma2 = 1), 
       nu = list(nu1 = 1, nu2 = 1), tau = list(tau1 = 1, tau2 = 1), 
       pi = list(pi1 = 0.2, pi2 = 0.8), family = list(fam1 = "NO", fam2 = "NO"), 
       log = FALSE, ...)
pMX(q, mu = list(mu1 = 1, mu2 = 5), sigma = list(sigma1 = 1, sigma2 = 1), 
       nu = list(nu1 = 1, nu2 = 1), tau = list(tau1 = 1, tau2 = 1), 
       pi = list(pi1 = 0.2, pi2 = 0.8), family = list(fam1 = "NO", fam2 = "NO"), 
       log = FALSE, ...)

Arguments

y,q	vector of quantiles
mu	a vector of mu's
sigma	a vector of sigma's
nu	a vector of nu's
tau	a vector of tau's
pi	a vector of pi's
family	a vector of GAMLSS family's
log	whether the log of the function or not
...	for extra arguments

Value

Returns values or pdf or cdf.

Examples

fyNO<-dMX(y=seq(0,3,.01), mu=list(1.253, 0.1876), sigma=list(exp(-0.6665 ), exp(-2.573 )),
                  pi=list(0.4079609, 0.5920391 ), family=list("NO","NO") )
plot(fyNO~seq(0,3,.01), type="l")                  
FyNO<-pMX(q=seq(0,3,.01), mu=list(1.253, 0.1876), sigma=list(exp(-0.6665 ), exp(-2.573 )),
                  pi=list(0.4079609, 0.5920391 ), family=list("NO","NO") )
plot(FyNO~seq(0,3,.01), type="l")
