I’ve got the power! Calculating statistical power for matching models by simulation

Jonathan Lain ICT4D, Real Geek

Calculating statistical power – or working out how many people to interview before a survey – can be a challenge, especially if we want to use matching models to estimate projects’ impacts. In this blog post, we discuss how computer simulations might make power calculations easier and explain how we’ve tried this out in the evaluation team at Oxfam. How …
