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 designing experiments and framing questions for statistical analysis. You'll also expand your statistics toolkit to include a suite of powerful hypothesis tests. WebApr 11, 2024 · With the best parameters for the polynomial fit determined (no filtering, kN = 150, degree = 1 (linear)), the fit was then used to test ground photon retrieval. For this, residuals were removed iteratively. First, the polynomial fit on the entire GT1L beam was calculated, smoothed and checked for effects from outlier photons.
