Interference, Bias, and Variance in Two-Sided Marketplace Experimentation: Guidance for Platforms
双边市场实验中的干扰、偏差与方差:平台实验设计指引
Two-sided marketplace platforms often run experiments to test the effect of an intervention before launching it platform-wide. A typical approach is to randomize individuals into the treatment group, which receives the intervention, and the control group, which does not. The platform then compares the performance in the two groups to estimate the effect if the intervention were launched to everyone. We focus on two common experiment types, where the platform randomizes…
