In my experience with R learners there are two basic types. The “show me the code and what it does and let me play” type and the “please give me step by step directions” type. I’ve broken the following tutorial … Continue reading →

R has great support for Holt-Winter filtering and forecasting. I sometimes use this functionality, HoltWinter & predict.HoltWinter, to forecast demand figures based on historical data. Using the HoltWinter functions in R is pretty straightforward. Let's say our dataset looks as follows; demand <- ts(BJsales, start = c(2000, 1), frequency = Read more »The post Holt-Winters forecast using ggplot2 appeared first on FishyOperations.

Game ResultsI recently made a post about developing an algorithm to predict the NBA playoffs, and I concluded with 2 predictions. Although Miami beat the Celtics to make my algorithm 1-0 in terms of predictions, it fell to 1-1 when the Thunder beat the Spurs. So, we are now at .500 . Considering that the algorithm was about 61.5% accurate over the whole season, this is to be expected.I made…
This is the initial post about the algorithm. See updates 1, 2, and 3 for more. The algorithm is currently 4-2 in the playoffs!OverviewI was struck by Martin O'Leary's recent post on predicting the Eurovision finals, which led me to decide that I wou...
This is the initial post about the algorithm. See updates 1, 2, and 3 for more. The algorithm is currently 4-2 in the playoffs!OverviewI was struck by Martin O'Leary's recent post on predicting the Eurovision finals, which led me to decide that I would try to predict NBA games using mathematical models. As the finals are ongoing, this is a quite timely decision! You can read through everything or scroll…
