👉 In mathematics, a rational statistical model is one that represents data with quantifiable and measurable attributes. It is often used in statistics to represent qualitative or ordinal variables as numerical values. These models are commonly used for analyzing categorical data, where each category can be represented by a unique number. For example, the heights of people could be modeled as a quantitative variable, such as inches tall, while the weights could be modeled as a quantitative variable, like pounds.
