- Appropriately Handling Missing Values for Statistical Modelling and Prediction - May 22, 2020Many statisticians in industry agree that blindly imputing the missing values in your dataset is a dangerous move and should be avoided without first understanding why the data is missing in the first place.
- Looking Normal(ly Distributed) - May 20, 2020This article investigates when some probability distributions look normal "enough" for a statistical test.
- Evidence Counterfactuals for explaining predictive models on Big Data - May 18, 2020Big Data generated by people -- such as, social media posts, mobile phone GPS locations, and browsing history -- provide enormous prediction value for AI systems. However, explaining how these models predict with the data remains challenging. This interesting explanation approach considers how a model would behave if it didn't have the original set of data to work with.
- Were 21% of New York City residents really infected with the novel coronavirus? - May 6, 2020Understanding the types of statistical bias that pop up in popular media and reporting is especially important during this pandemic where the data -- and our global response to the data -- directly impact peoples' lives.
