Statistical Analysis of Case Recovery Rate

Abstract

This paper propose to develop statistical measures of case recovery rate assuming that patient recovery is influenced by two factors acting simultaneously, that is, to develop a two way analysis of case recovery rate for a disease. The specific rates which are useful in identifying segments of the population that are at elevated risk of a given disease and would need a more aggressive medical and health interventionist measures to alleviate the disease compared with the average number of the general population at risk were estimated. Case recovery rate has shown to possibly serve as a measure of morbidity of a disease in a population especially if the disease is not virulent.  It is shown that the smaller this rate is, the more likely is the disease morbid in the population and vice versa.  It is also shown under certain condition that case recovery rate when used as a measure of survivorship or morbidity from a disease must be used and interpreted with great caution because of definitional problems. The propose method was illustrated with some data.
