View source: R/ProbYX.R

Description

Compute maximum likelihood estimates of R, considered as the parameter of interest. Maximum likelihood estimates of the nuisance parameter are also supplied.

Usage

1
MLEs(ydat, xdat, distr)

Arguments

ydat

data vector of the sample measurements from Y.

xdat

data vector of the sample measurements from X.

distr

character string specifying the type of distribution assumed for Y and X. Possible choices for distr are "exp" (default) for the one-parameter exponential, "norm_EV" and "norm_DV" for the Gaussian distribution with, respectively, equal or unequal variances assumed for the two random variables.

Details

The two independent random variables Y and X with given distribution distr are measurements of a certain characteristics on two different populations. For the relationship of the parameter of interest (R) and nuisance parameters with the original parameters of distr, look at the details in loglik.

Value

Vector of estimetes of the nuisance parameters and the R quantity (parameter of interest), respectively.
