The Atlantic Daily: 9 Nostalgic TV Shows to Watch

Every weekday evening, our editors guide you through the biggest stories of the day, help you discover new ideas, and surprise you with moments of delight. Subscribe to get this delivered to your inbox . A worsening pandemic may leave many Americans stripped of holiday comforts. Although an old TV show is no substitute for a hug from a loved one, perhaps some solace can be found in the familiar faces of beloved characters . I asked writers and editors from around our newsroom to share a nostalgic TV pick. TWIN PEAKS (NETFLIX) Twin Peaks , a disorienting mystery about the murder of a beloved high schooler, isn’t exactly built for bingeing. But the early-’90s cult phenomenon from David Lynch and Mark Frost remains an enthralling watch. Its masterpiece of a first season takes its time , challenging the viewer by slowly doling out reveals and creating a sense that everything and everyone—even the characters investigating the case—are just a little off .

Round about the kernel

[This article was first published on R on OSM , and kindly contributed to R-bloggers ]. (You can report issue about the content on this page here ) Want to share your content on R-bloggers? click here if you have a blog, or here if you don't. In our last post , we took our analysis of rolling average pairwise correlations on the constituents of the XLI ETF one step further by applying kernel regressions to the data and comparing those results with linear regressions. Using a cross-validation approach to analyze prediction error and overfitting potential, we found that kernel regressions saw average error increase between training and validation sets, while the linear models saw it decrease.
