R with Power BI: Import, Transform, Visualize and Share


Power BI, Microsoft's data visualization and reporting platform, has made great strides in the past year integrating the R language. This Computerworld article describes the recent advances with Power BI and R. In short, you can: Power BI desktop is completely free to download and use, and includes all the features you need to create visualizations, reports and dashboards. Power BI desktop and R are both included in the Data Science Virtual Machine, so that's another easy way to get started. Sharon Laivand from the Power BI engineering team recently gave a webinar showcasing the capabilities of Power BI and R. Fast-forward to the 29-minute mark to see how to create a report incorporating R-based calculations and graphics, and then share it with others (even people who don't have R installed!) using Power BI online.

Power-Law Distributions in Empirical Data SIAM Review Vol. 51, No. 4


Power-law distributions occur in many situations of scientific interest and have significant consequences for our understanding of natural and man-made phenomena. Unfortunately, the detection and characterization of power laws is complicated by the large fluctuations that occur in the tail of the distribution--the part of the distribution representing large but rare events--and by the difficulty of identifying the range over which power-law behavior holds. Commonly used methods for analyzing power-law data, such as least-squares fitting, can produce substantially inaccurate estimates of parameters for power-law distributions, and even in cases where such methods return accurate answers they are still unsatisfactory because they give no indication of whether the data obey a power law at all. Here we present a principled statistical framework for discerning and quantifying power-law behavior in empirical data. Our approach combines maximum-likelihood fitting methods with goodness-of-fit tests based on the Kolmogorov–Smirnov (KS) statistic and likelihood ratios.
