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.

`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 |

For more details see the package vignette

`estimate` |
estimate of the variance component |
