Heterogeneous treatment effects

  • Heterogeneous treatment effects and homogeneous outcome variances

    6 min read R

    Recently there has been a couple of meta-analyses investigating heterogeneous treatment effects by analyzing the ratio of the outcome variances in the treatment and control group. The argument made in these articles is that if individuals differ in their response, then observed variances in the treatment and control group in RCTs should differ. In this post I explore this argument and provide a counterargument.
