Hi,

I'm not sure how use curve(dexGAUS(…

None of the following four works:

rt<- rexGAUS(100, mu=300, nu=100, sigma=35)
m1<-gamlss(rt~1, family=exGAUS)
curve(dexGAUS(rt=x, mu=300 ,sigma=35,nu=100), 100, 600, main = "The ex- 
GAUS  density mu=300 ,sigma=35,nu=100")
curve(dexGAUS(x=rt, mu=300 ,sigma=35,nu=100), 100, 600, main = "The ex- 
GAUS  density mu=300 ,sigma=35,nu=100")
curve(dexGAUS(y=rt, mu=300 ,sigma=35,nu=100), 100, 600, main = "The ex- 
GAUS  density mu=300 ,sigma=35,nu=100")
curve(dexGAUS(rt=y, mu=300 ,sigma=35,nu=100), 100, 600, main = "The ex- 
GAUS  density mu=300 ,sigma=35,nu=100")
But this does:

y<- rexGAUS(100, mu=300, nu=100, sigma=35)
m1<-gamlss(y~1, family=exGAUS)
curve(dexGAUS(y=x, mu=300 ,sigma=35,nu=100), 100, 600, main = "The ex- 
GAUS  density mu=300 ,sigma=35,nu=100")
