Feed: R-bloggers. Author: Gavin L. Simpson. One of the specialist smoother types in the mgcv package is the Markov Random Field (MFR) smooth. This smoother essentially allows you to model spatial data with an intrinsic Gaussian Markov random field (GMRF). GRMFs are often used for spatial data measured over discrete spatial regions. MRFs are quite flexible as you can think about them as representing an undirected graph whose nodes are your samples and the connections between the nodes are specified via a neighbourhood structure. I’ve become interested in using these MRF smooths to include information about relationships between species. However, ... Read More

Feed: R-bloggers. Author: Branden Dunbar. At Plotly, we are commonly asked about thematic maps — especially county-level choropleth maps. This style of map provides a visual illustration of variation across a geographic area. Some pertinent uses are population density, economic measurements, crime statistics, and election results. With Plotly, there are multiple ways to bring county-level choropleths to life. For example, using ggplotly or native plot_ly or plot_mapbox . . . For now, we will look at how to create the US electoral map using the ggplotly method. For more information concerning the plot_ly and plot_mapbox examples, checkout our R documentation library.   ... Read More

Feed: R-bloggers. Author: Peter Laurinec. Ensemble learning methods are widely used nowadays for its predictive performance improvement. Ensemble learning combines multiple predictions (forecasts) from one or multiple methods to overcome accuracy of simple prediction and to avoid possible overfit. In the domain of time series forecasting, we have somehow obstructed situation because of dynamic changes in coming data. However, when a single regression model is used for forecasting, time dependency is not the obstacle, we can tune it at current time of a sliding window. For this reason, in this post, I will describe you two simple ensemble learning methods ... Read More

When the company first launched as an online bookseller in 1994, consumer confidence in online shopping was low, to say the least. Exclusively competing with local bookstores, Amazon and many e-tailers throughout the 90s and early 2000s had to work to create trust in online shopping. Their efforts paid off, ushering in a new era and transforming the way we all shop today. Amazon is a good example of digital trust making a brand. But data ... Read More

While the team did a wonderful job of preparing me and all the speakers at this event, the one thing I was unprepared for is how different the view is from backstage.
