Handy statistical lexicon. These are all important methods and concepts related to statistics that are not as well known as they should be.
I hope that by giving them names, we will make the ideas more accessible to people: Mister P: Multilevel regression and poststratification. The Secret Weapon: Fitting a statistical model repeatedly on several different datasets and then displaying all these estimates together. The Superplot: Line plot of estimates in an interaction, with circles showing group sizes and a line showing the regression of the aggregate averages. The Folk Theorem: When you have computational problems, often there’s a problem with your model. The Pinch-Hitter Syndrome: People whose job it is to do just one thing are not always so good at that one thing. Weakly Informative Priors: What you should be doing when you think you want to use noninformative priors. P-values and U-values: They’re different. Conservatism: In statistics, the desire to use methods that have been used before.
P.S. 40 Techniques Used by Data Scientists. These techniques cover most of what data scientists and related practitioners are using in their daily activities, whether they use solutions offered by a vendor, or whether they design proprietary tools.
When you click on any of the 40 links below, you will find a selection of articles related to the entry in question. Most of these articles are hard to find with a Google search, so in some ways this gives you access to the hidden literature on data science, machine learning, and statistical science. Asdfree.

Today we’re going to be talking about statistics, p-values, and the multiple comparisons problem. Some good background resources here are: For my own benefit, I’ll try and explain what follows as simply as possible – I find it incredibly easy to make mistakes otherwise! Let’s start with a very quick recap of p-values. Anscombe's quartet. All four sets are identical when examined using simple summary statistics, but vary considerably when graphed Anscombe's quartet comprises four datasets that have nearly identical simple descriptive statistics, yet appear very different when graphed.
Each dataset consists of eleven (x,y) points. They were constructed in 1973 by the statistician Francis Anscombe to demonstrate both the importance of graphing data before analyzing it and the effect of outliers on statistical properties. He described the article as being intended to attack the impression among statisticians that "numerical calculations are exact, but graphs are rough.

Mathematicians mapped out every “Game of Thrones” relationship to find the main character — Quartz. Fans of the Game of Thrones books and TV series have long quarreled over who the true hero of the story is.
Daenerys? Tyrion? Jon Snow? Hodor? Every time a character seems to be developing into a protagonist, he or she is brutally killed (video). But several main characters remain. Andrew J. The books and HBO fantasy series, with their massive cast of characters, various shifting allegiances, and intricate relationship dynamics, were a perfect fit to be studied mathematically. “This is a fanciful application of network science,” Beveridge told Quartz. The pair started by connecting characters every time they “interacted” in the third book of the series, A Storm of Swords. The resulting network structure (above) broke the characters into extremely accurate communities that show the geographical, familial, and even adversarial ties between them.
“We didn’t tell it what the communities were, the network actually tells you what the communities are,” Beveridge said. Math 101: A reading list for lifelong learners. Ready to level up your working knowledge of math?

Top 50 Free Statistical Software. How I Acted Like A Pundit And Screwed Up On Donald Trump. Since Donald Trump effectively wrapped up the Republican nomination this month, I’ve seen a lot of critical self-assessments from empirically minded journalists — FiveThirtyEight included, twice over — about what they got wrong on Trump.
This instinct to be accountable for one’s predictions is good since the conceit of “data journalism,” at least as I see it, is to apply the scientific method to the news. That means observing the world, formulating hypotheses about it, and making those hypotheses falsifiable. Best Data Science Online Courses. The number of online data science courses have exploded in recent years and there courses for any needs.

How many times have you heard managers and colleagues complain about the quality of the data in a particular report, system or database? People often describe poor quality data as unreliable or not trustworthy. Defining exactly what high or low quality data is, why it is a certain quality level and how to manage and improve it is often a trickier task. Data Science - Part II - Working with R & R Studio. The Season for Sharing Data: Working with the newly released Census 2010-2014 ACS 5 year data in R. On December 3, 2015 the U.S. Census Bureau released the 2010-2014 5 year ACS (American Community Survey) data. You can read all about it on the Census website. This fantastic five-year statistical database provides aggregate social and economic characteristics about American individuals and families down to the block group level.
A number of online tools provide access to the ACS 2010-2014 data using graphical user interfaces (GUIs). These include the Census American FactFinder tool or via Social Explorer. 20 Big Data Repositories You Should Check Out. RepASA. Deducer: A GUI for R - Deducer Manual. LeaRning Path on R - Step by Step Guide to Learn Data Science on R. One of the common problems people face in learning R is lack of a structured path. They don’t know, from where to start, how to proceed, which track to choose?
Though, there is an overload of good free resources available on the Internet, this could be overwhelming as well as confusing at the same time. To create this R learning path, Analytics Vidhya and DataCamp sat together and selected a comprehensive set of resources to help you learn R from scratch. This learning path is a great introduction for anyone new to data science or R, and if you are a more experienced R user you will be updated on some of the latest advancements. This will help you learn R quickly and efficiently. Step 0: Warming up Before starting your journey, the first question to answer is: Why use R?
