Bayesian Estimation of Variance under Fine Stratification via Mean-Variance Smoothing
Sepideh Mosaferi, Shonosuke Sugasawa
Fine stratification survey is useful in many applications as its point estimator is unbiased, but the variance estimator under the design cannot be easily obtained, particularly wh…
Optimal Change Point Detection and Inference in the Spectral Density of General Time Series Models
Sepideh Mosaferi, Abolfazl Safikhani, Peiliang Bai
This paper addresses the problem of detecting change points in the spectral density of time series, motivated by EEG analysis of seizure patients. Seizures disrupt coherence and fu…
Properties of Test Statistics for Nonparametric Cointegrating Regression Functions Based on Subsamples
Sepideh Mosaferi, Mark S. Kaiser, Daniel J. Nordman
Nonparametric cointegrating regression models have been extensively used in financial markets, stock prices, heavy traffic, climate data sets, and energy markets. Models with param…
An Unbiased Predictor for Skewed Response Variable with Measurement Error in Covariate
Sepideh Mosaferi, Malay Ghosh, Shonosuke Sugasawa
We introduce a new small area predictor when the Fay-Herriot normal error model is fitted to a logarithmically transformed response variable, and the covariate is measured with err…
Nonparametric Cointegrating Regression Functions with Endogeneity and Semi-Long Memory
Sepideh Mosaferi, Mark S. Kaiser
This article develops nonparametric cointegrating regression models with endogeneity and semi-long memory. We assume that semi-long memory is produced in the regressor process by t…
A Bayesian Approach for the Variance of Fine Stratification
Sepideh Mosaferi
Fine stratification is a popular design as it permits the stratification to be carried out to the fullest possible extent. Some examples include the Current Population Survey and N…
An application of a small area procedure with correlation between measurement error and sampling error to the Conservation Effects Assessment Project
Emily Berg, Sepideh Mosaferi
County level estimates of mean sheet and rill erosion from the Conservation Effects Assessment Project (CEAP) are useful for program development and evaluation. Since county sample…
Transformed Fay-Herriot Model with Measurement Error in Covariates
Sepideh Mosaferi, Malay Ghosh, Rebecca C. Steorts
Statistical agencies are often asked to produce small area estimates (SAEs) for positively skewed variables. When domain sample sizes are too small to support direct estimators, ef…
Empirical and Constrained Empirical Bayes Variance Estimation Under A One Unit Per Stratum Sample Design
Sepideh Mosaferi
A single primary sampling unit (PSU) per stratum design is a popular design for estimating the parameter of interest. Although, the point estimator of the design is unbiased and ef…
A Recommendation for Net Undercount Estimation in Iran Population and Dwelling Censuses
Sepideh Mosaferi, Hamidreza Navvabpour
Census counts are subject to different types of nonsampling errors. One of these main errors is coverage error. Undercount and overcount are two types of coverage error. Undercount…
Spatio-Temporal Mixed Models to Predict Coverage Error Rates at Local Areas
Sepideh Mosaferi
Despite of the great efforts during the censuses, occurrence of some nonsampling errors such as coverage error is inevitable. Coverage error which can be classified into two types…
