Warner proposed a methodology called randomized response techniques, which, through the random scrambling of sensitive variables, allows non-response rate to be reduced and bias diminished. In this document, we present technique using simple sampling. The variable is performed selection report Ri, i = 1,2,3. order evaluate accuracy efficiency estimators, simulation was carried out with two data...

An attempt has been made to estimate reliability for mean of normal population with known CV. The function is derived and curves have shown this function. It seen that effect skewness considerable but the kurtosis not much.

Introduction: Pulmonary hypertension has been associated with a significant increase in morbidity and mortality. The pulmonary artery diameter measurement from CT scan is routinely used to predict possible evidence of hypertension. However, no data available as reference for the normal range, especially Thai Population. primary purpose this study was determine main (MPA) ascending aorta (AAo) r...
