Our discussion of regression will concentrate on linear regression. Its central idea is to find the straight line that "best" fits a set of observed points, i.e., observed pairs of values of two variables. With observed data we often have problems of minor errors of measurement and with the effects of chance deviations from some underlying pattern. For example, height and weight data are subjec...

The reliability of drug consumption studies will depend on agreement on an international unit of measurement and the provision of accurate descriptions of patterns of use. This measurement unit should permit comparisons between countries and periods of time. Different units have been proposed and published. Consumption may be expressed in terms of pharmaceutical firm turnover, therapeutic costs...

Measurement is the means of collecting data from patients whether for purpose of research or for decision making in clinical practice. The commonest method of measurement used in research or practice is simply by observation. An obvious example is the physical examination of patients by a clinical investigator or by a doctor. Another familiar method is the use of equipment like in chemical meas...

In the area of mass production, the products are weighed using load cell based weighing system. A load cell is an uncontrollable weighing device. Improvement in filtering increases the speed of weighing and enhances the measurement accuracy. In this paper, a novel algorithm and architecture is proposed for the weighing system. The algorithm has been verified and implemented in the weight measur...

Objective: We aimed to evaluate the bone turnover markers in preterm infants, and analyze their relationship with growth, urinary calcium (Ca) and phosphorus (P). Subjects and Method: Thirty-nine premature infants with enteral feeding started before the 5th day of life, and 20 full-term infants, as control group, were enrolled for the study. The weight and length of all premature infants were m...
