Understanding Count Variables
Count variables are integral to various analytical models, particularly regression. They represent discrete outcomes that are governed by integers with a lower bound at zero, such as the frequency of occurrences in specific contexts, like hospital admissions or substance use. The podcast emphasizes the importance of correctly modeling these variables to avoid violating core assumptions of traditional regressions, which can lead to incorrect results. Exploring examples like consumption frequencies illustrates the relevance of proper analysis methods for these count data.
