    » Parameter Estimation of Cobb Douglas Production Function with Multiplicative and Additive Errors using the Frequentist and Bayesian Approaches

    » J.O. Iyaniwura, A. Adedayo Adepoju and Oluwaseun A. Adesina


    Nonlinear Models are generally classified as intrinsically nonlinear and intrinsically linear based on the specification of the errors. This study was aimed at estimating the parameters of Cobb-Douglas production function with additive and multiplicative errors using the classical and Bayesian approaches. The classical nonlinear method considered is the Gauss-Newton iterative Method while the Bayesian estimation was carried out using the Metropolis-within-Gibbs with independent normal-Gamma prior. For the classical, the results showed that the estimates of the parameters of the Cobb-Douglas function with additive errors performed better than those for the multiplicative errors. However, similar estimates were obtained for both multiplicative and additive errors for the Bayesian approach. Overall, the Bayesian method performed better than the classical approach.

    » A Modified Ratio Techniques in Successive Sampling on Two Occasions

    » K. O. Adetunji and A. O. Adejumo


    Successive sampling is a known technique that can be used in longitudinal surveys to estimate population parameter and measurement of change or sum of study variables and auxiliary variables. However, the problem of ratio estimation is incorporated to successive sampling on the samples selected over two occasions has been considered. This study aimed at proposed Ratio Estimator technique in the context of devising efficient sampling strategies for estimators. The three estimators used as the instrument for parameter estimation in the successive sampling are Simple Estimator (SEst), Linear Estimator (LEst) and proposed Ratio Estimator (PRATEst). The proposed Ratio Estimator procedure was obtained through the properties of biasness, mean square Error (MSE), minimum mean square Errors (MMSE) and Efficiency comparison (EC). Two sets of Real life data were used in this study. The first data was collected from National Population Commission (NPC) of the census conducted in Nigeria for year 1991 and 2006, also the second data set was collected from ministry of education and human capital development on the teachers and students enrolment for 2013/2014 and 2016/2017 academic sessions. In, conclusion, it is clear and also visible that proposed estimator (PRATEst) μ_PRATE=(˥x)/(˥y)*(˥z) is highly rewarding than conventional ones μ_SE=(˥x),(˥y) and (˥z) ̅and μ_LE=(˥x)(˥y),(˥x)(˥z) and (˥y)(˥z) therefore, the proposed estimator is recommended for use in successive sampling scheme.
