ABSTRACT
Regression analyses are tools essential to the applied researcher in many instances. Regression is a statistical methodology that uses the relationship between two or more quantitative variables such that the value of one variable can be predicted based on the value(s) of the other(s) [25]. Determining the relationship between two variables, such as exposure time and lethality or wash time and log10 microbial reductions, is very common in applied research. From a mathematical perspective, two relationships are worth discussing: (1) a functional relationship and (2) a statistical relationship.
