R help - Feb 2009 - The effect of MLE and MME to probability of rejection

Hi I am beginner with R

 

I would like to compare the performance of Maximum likelihood Estimator
(MLE) and Method of Moment Estimator (MME) effect probability of rejection,
p. My MLE is 

x=rlnorm(10,meanlog = 2, sdlog =5)

x

xbar=mean(x)

ssqrt=var(x)

xbar

ssqrt

 

#MLE

y=log(x)

m1=mean(y)

s1=var(y)

m1

s1

 

#MME

m2=log(xbar^2/sqrt(ssqrt+xbar^2))

s2 = log((ssqrt+xbar^2)/xbar^2)

m2

s2

 

If  I want  to use "qlnorm(..)" , where can I plug the above
estimators into
this function. 

 

 

Regards
