Feed: R-bloggers. Author: Method Matters. In this post, we will solve a simple problem (called “FizzBuzz“) that is asked by some employers in data scientist job interviews. The question seeks to ascertain the applicant’s familiarity with basic programming concepts. We will see 2 different ways to solve the problem in 2 different statistical programming languages: R and Python. The FizzBuzz Question I came across the FizzBuzz question in this excellent blog post on conducting data scientist interviews and have seen it referenced elsewhere on the web. The intent of the question is to probe the job applicant’s knowledge of basic ... Read More

Feed: R-bloggers. Author: Analysis of AFL. I got an email from Alex Zanidean, who runs the xmrr package “You might enjoy my package xmrr for similar charts – but mine recalculate the bounds automatically” and if we go to the vingette, “XMRs combine X-Bar control charts and Moving Range control charts. These functions also will recalculate the reference lines when significant change has occurred” This seems like a pretty handy thing. So lets do it. First lets do our graphic from our previous post using ggQC library(fitzRoy) library(tidyverse) ## ── Attaching packages ───────────────────────────────────────────────────────── tidyverse 1.2.1 ── ## ✔ ggplot2 3.1.1 ...

My eye was caught by this tweet by Robin Wigglesworth of the Financial Times with an Alan Smith animation of the US Treasury yield curve from 2005 to 2009. It’s a nice graphic and it made me wonder what it would look like over a longer period.The “yield curve” is the name given to the graphic showing the different annual rates paid on investors who in effect lend money to the US Treasury. In normal circumstances, investors who are prepared to make the loan on a long term basis demand higher effective ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Packt Publishing. The diverse fields in which machine learning has proven its worth is nothing short of amazing. At the heart of machine learning are the various algorithms it employs to classify data and predict outcomes. This article highlights two greedy classifiers that, albeit simple, can be extremely powerful in their own right.   This article is an excerpt from the book Machine Learning with R, Third Edition, written by Brett Lantz. This book provides a hands-on, readable guide to applying machine learning to real-world problems. Whether you are an experience ... Read More

Feed: R-bloggers. Author: Bob Muenchen. Introduction JASP is a free and open source statistics package that targets beginners looking to point-and-click their way through analyses. This article is one of a series of reviews which aim to help non-programmers choose the Graphical User Interface (GUI) for R, which best meets their needs. Most of these reviews also include cursory descriptions of the programming support that each GUI offers. JASP stands for Jeffreys’ Amazing Statistics Program, a nod to the Bayesian statistician, Sir Harold Jeffreys. It is available for Windows, Mac, Linux, and there is even a cloud version. One of JASP’s key features ... Read More

Feed: R-bloggers. Author: Chuck Powell. I recently had the need to run an ANCOVA, not a task I perform all thatoften and my first time using R to do so (I’ve done it in SPSS andSAS before). Having a decent theoretical idea of what I had to do Iset off in search of decent documentation on how to accomplish it in R. Iwas quite disappointed with what I found after a decent amount of timescouring the web (or at least I thought so). I found “answers” in placeslike “Stack Overflow” and “Cross Validated” as well as various free andopen notes ... Read More

If you ever dreamt of automating the first, laborious part of data analysis when you get to know the variables, print descriptive statistics, draw a lot of histograms and scatter plots – you weren’t the only one. Turns out that a lot of R developers and users thought of the same thing. There are over a dozen R packages for automated Exploratory Data Analysis and the interest in them is growing quickly ...

Feed: Planet MySQL; Author: MySQL Performance Blog; PREVIOUS POST Python 2 reaches EOL on 2020-01-01 and one of its commonly used third-party packages is MySQL-python. If you have not yet migrated away from both of these, since MySQL-python does not support Python 3, then you may have come across some issues if you are using more recent versions of MySQL and are enforcing a secured installation. This post will look at two specific issues that you may come across (caching_sha2_password in MySQL 8.0 and TLSv1.2 with MySQL >=5.7.10 when using OpenSSL) that will prevent you from connecting to a MySQL ...
