Description Usage Arguments Details Value Author(s) References See Also Examples

This function returns a list with one element in it which is the estimate of the variance component in the Fay Herriot Model using residual maximum likelihood method. The estimates are obtained as a solution of equations known as REML equations. The solution is obtained numerically using Fisher-scoring algorithm. For more details please see the package vignette and the references. Note that our function does not accept any missing values.

1	resimaxilikelihood(response, designmatrix, sampling.var,maxiter)

`response`	a numeric vector. It represents the response or the observed value in the Fay Herriot Model
`designmatrix`	a numeric matrix. The first column is a column of ones(also called the intercept). The other columns consist of observations of each of the covariates or the explanatory variable in Fay Herriot Model.
`sampling.var`	a numeric vector consisting of the known sampling variances of each of the small area levels.
`maxiter`	maximum number of iterations of fisher scoring
