WEB8.1. Introduction. In research we are often interested in quantifying some characteristic of a population, such as the prevalence of a condition, the average of a measurement, or the association between an exposure and a disease. Typically, we measure the characteristic in a sample of units from the population and use that information to make

In this chapter, you will learn how to: Identify a time-to-event outcome; Identify types and mechanisms of censoring; Interpret the survival and hazard functions; Use the Kaplan-Meier method to estimate the survival function; Use the log-rank test to compare survival between groups; Visualize the Kaplan-Meier
Chapter 10 Poisson regression Data Analysis in Medicine and …
WEB10.2 Introduction. Poisson regression is a regression analysis for count and rate data. As mentioned before in Chapter 7, it is is a type of Generalized linear models (GLMs) whenever the outcome is count. It also accommodates rate data as we will see shortly. Although count and rate data are very common in medical and health sciences, in our

5.18 Box-Cox outcome transformation
WEB5.18. Box-Cox outcome transformation. Continuous variables that are highly skewed are common in public health. For example, any variable that is derived as the sum of multiple indicators will have all non-negative values and this often leads to a skewed distribution. For example, in Rogers et al. ( 2021), researchers log-transformed the skewed
6.2 Interpretation of the logistic regression coefficients
WEB6.2 Interpretation of the logistic regression coefficients. How do we interpret the logistic regression coefficients? First, we need to get into some math. In the end, we will use R to do all the computations for us; however, it is important to see the math to understand how to interpret a logistic regression model.
