Unified and Simple Sample Size Calculations for Individual or Cluster Randomized Trials with Skewed or Ordinal Outcomes
Shengxin Tu, Chun Li, Caroline De Schacht +4
Sample size calculations can be challenging with skewed continuous outcomes in randomized controlled trials (RCTs). Standard t-test-based calculations may require data transformati…
Between- and Within-Cluster Spearman Rank Correlations
Shengxin Tu, Chun Li, Bryan E. Shepherd
Clustered data are common in practice. Clustering arises when subjects are measured repeatedly, or subjects are nested in groups (e.g., households, schools). It is often of interes…
Rank Intraclass Correlation for Clustered Data
Shengxin Tu, Chun Li, Donglin Zeng +1
Clustered data are common in biomedical research. Observations in the same cluster are often more similar to each other than to observations from other clusters. The intraclass cor…
Addressing Detection Limits with Semiparametric Cumulative Probability Models
Yuqi Tian, Chun Li, Shengxin Tu +3
Detection limits (DLs), where a variable is unable to be measured outside of a certain range, are common in research. Most approaches to handle DLs in the response variable implici…
