Pooled estimate hypothesis testing
WebIn this work, we develop a penalized doubly robust method to estimate the optimal individualized treatment rule from high-dimensional data. We propose a split-and-pooled de-correlated score to construct hypothesis tests and confidence intervals. WebStatistics is essential for achieving all of those goals, and this course will teach you the methods you need to make the most of your data. You'll gain hands-on experience …
