Categorical data analysis
Categorical data analysis was used to analyze continuous data in this study. The basic problem with categorical data analysis applied to continuous data is that an emic perspective is imposed upon the data. For instance. WHO identifies a low perinatal mortality rate as <=20/1000 while a high perinatal mortality rate is >20/1000. One death per 1000 switches a nation from one status to the other. It is better to first conduct a multiple linear-regression analysis to determine natural categories within the data rather than just using categorical analysis with continuous data.
