Using Observational Vs Randomized Controlled Trial Data to Learn about Treatment Effects

Randomized controlled trials (RCTs) are routinely used in medicine and are becoming more popular in economics. Data from RCTs are used to learn about treatment effects of interest. This paper studies what one can learn about the average treatment response (ATR) and average treatment effect (ATE) from RCT data under various assumptions and compares that to using observational data. We find that ...

Using Mimicry to learn about Phonology

We often think of intonational phonology in terms of discrete entities: accents which fall into just a few categories (Gussenhoven 1999; Ladd 1996; Beckman and Ayers Elam 1997). In this view, accents in intonation correspond to phonemes in segmental phonology (except that they cover a larger interval). They have a rough correspondence to the acoustic properties of the relevant region and they a...

Using Simulation to Learn about Inference

Many statistics educators use simulation to help students better understand inference. Simulations make the link between statistics and probability explicit through simulating the conditions of the null hypothesis, and then looking at sampling distributions of an appropriate measure. In this paper we review how we use simulation to help understand hypothesis testing, and lay out the relevant st...

Using Mimicry to Learn about Mental Representations

Phonology typically describes speech in terms of discrete signs like features. The field of intonational phonology uses discrete accents to describe intonation and prosody. But, are such representations useful? The results of mimicry experiments indicate that discrete signs are not a useful representation of the shape of intonation contours. Human behaviour seems to be better represented by a a...
