Models
======

1. One predictor
  sesame_one_pred_2b.stan: lm(y ~ watched_hat)
  sesame_one_pred_a.stan : lm(watched ~ encouraged)
  sesame_one_pred_b.stan : lm(y ~ encouraged)

3. Multiple predictors without interaction
  ideo_reparam.stan        : lm(score1 ~ party + z1 + z2)
  ideo_two_pred.stan       : lm(score1 ~ party + x)
  sesame_mult_preds_3a.stan: lm(y ~ encouraged + pretest + factor(site) + setting)
  sesame_mult_preds_3b.stan: lm(y ~ watched_hat + pretest + factor(site) + setting)

3. Multiple predictors with interaction
  ideo_interactions.stan: lm(score1 ~ party + x + party:x)
