Table S1. Summary of models planned and coded in Stage 1 of registered report. (To be included in Supplementary Materials at Stage 2).
Group difference tests:
Main model(s) in code:
H1 Linear model with ethnic groups as dummy variables, with age as an additional covariate.
h1
H4 Initial comparison of City and Rural.
Development and size rank will be entered as a predictor in linear models with a dummy Mestizo-ethnicity variable and age as covariates.
These will be followed up with descriptive spline models (using AIC to select amongst models with up to 4 knots) to account for rank being ordinal.
H4cf, h4cm H4rf, h4rm
H4rf.s, h4rm.s
Individual effects tests:
All run using mixed effects models with community as a clustering variable. All main analyses run separately for male and female faces where applicable.
Individual level predictors will be:
H2 (women only)
Linear and quadratic terms for age
Secondary analysis with dummy variables (<20, 20-44, 45+)
h2.1 h2.2 H3 (women
only)
Dummy variable (cohabiting relationship or not) and age h3 H5a,b Combined status (summed z scores of yrs education and income in
USD)
Education (years), income (total in dollars), and age
h5mfo, h5fmo h5mfs, h5fms, h5exp
H6 Hours of television in the last week (using Natural logarithm if skewed as in previous papers) in first model (already run in original 264 pp); any other correlates of television identified in zero order correlations will be added in subsequent model (not yet run).
