An interactive graphical summary of findings from a recently published review of 103 compositional isotemporal substitution studies.
R code for CoDa functional regression and isotemporal substitution analysis
The loss of potentially important information that occurs when the time spent in physical activity is collapsed into broad intensity categories can be avoided by analysing accelerometer data as probability density functions. More information about the compositional scalar-on-function regression and newly developed compositional functional isotemporal substitution analysis can be found here.
Stacked CoDA model
R code for a multi-level regression model with compositional data as dependent variables. Detailed information about the model and an example analysis can be found here.
Compositional PLS biplots with pivoting balances
R code for creating compositional PLS biplots when examining associations between a time-use composition and a health outcome. Detailed information about the procedure and an example analysis can be found here.

R code for compositional data analysis (CoDA) in time-use epidemiology
R code, examples, and instructions for conducting descriptive analysis of compositional data, compositional isotemporal substitution analysis, regression analysis with a time-use composition as the outcome, and a regression analysis with a time-use composition as explanatory variables
