Subhasish Misra (Walmart Labs)
Causal questions are ubiquitous, and randomized tests are considered the gold standard. However, such tests are not always feasible, and then you just have observational data to get to causal insights. But techniques such as matching offer an opportunity to solve this. Subhasish Misra explores this and practical tips when trying to infer causal effects. Read more.
