Self-actualization has been studied among various occupational groups such as managers, supervisors, administrators, counselors, principles teachers and secondary school boys and girls. The objectives of the study were to find difference in self – actualization of boys and girls, boys and girls studying in 9th and 10th class, boys studying in 9th class and 10th class and girls studying in 9th a...

This study assesses the effectiveness of stratification, based on photo-interpreted forest types, for strategic inventory. It uses results (from stratified sampling) for Total Merchantable Volume (TMV) in 18 Inventory Areas in Tasmanian State forest. The variance of the TMV as determined from stratified sampling is compared with the estimated variance of a simple random sample using the same nu...

7.1 Introduction In mail surveys, it is observed that the data may not be obtained in the first attempt, sometimes due to absenteeism and sometimes due to the refusal of the subject. This problem was first considered by Hansen and Hurwitz (1946), in which the population was divided into the groups of respondents and non respondents. They determine the sample size to be attempted on the first oc...

T paper describes, analyzes and evaluates an algorithm for estimating portfolio loss probabilities using Monte Carlo simulation. Obtaining accurate estimates of such loss probabilities is essential to calculating value-at-risk, which is a quantile of the loss distribution. The method employs a quadratic (’’delta-gamma’’) approximation to the change in portfolio value to guide the selection of e...

This study examines the efficiency of EPI cluster sampling in assessing the prevalence of diarrhoea and dysentery. A computer was used to simulate fieldwork carried out by a survey taker. The bias and variance of prevalence estimates obtained using EPI cluster sampling were compared with those obtained using simple random sampling and cluster (stratified random) sampling. Efficiency ratios, cal...
