Inference for Categorical Variables
Parametric One-Sample Inference of Categorical Variables
- one-sample proportion test
- do NOT use Yate's continuity, so specify:
- prop.test(…, correct = FALSE)
- $\Chi^2$ goodness of fit test
- to ensure sufficient sample size: $n \cdotp_{0} > 5$
- don't use continunity corrections!
- chisq.test(…, correct = FALSE)
NOTE: one-sample single proportion give a 95% CI – $\Chi^2$ does not!
- QI
- Stepped-wedge trial
- Linear regression
- plot of residuals
- these are different!
- correlative
- descriptive
- predictive
- associative
- confounding vs. effect modification
to assess a paired difference
- create histogram
- plot as box plot
- make Q-Q plot
