A Simple Explanation for the Replication Crisis in Science

By now, you’ve probably heard of the replication crisis in science. In summary, many conclusions from experiments done in a variety of fields have been found to not hold water when followed up in subsequent experiments. There are now any number of fa...

Evil collaboration between Medtronic and FDA

August 23, 2016
By

Paul Alper points us to this news article by Jim Spencer and Joe Carlson that has this amazing bit: Medtronic ran a retrospective study of 3,647 Infuse patients from 2006-2008 but shut it down without reporting more than 1,000 “adverse events” to the government within 30 days, as the law required. Medtronic, which acknowledges it […] The post Evil collaboration between Medtronic and FDA appeared first on Statistical Modeling, Causal…

Quote of the month

August 23, 2016
By

In a post titled "GIGO" (for those who don't like acronyms, Garbage In, Garbage Out), Andrew Gelman wrote this gem: as long as the “garbage out” gets media attention, there will always be somebody willing to supply the “garbage in.” The general drift of that post, and the previous one that led me to it, is a critique of the management consulting industry. Having worked in that industry earlier in…

Bayesian inference completely solves the multiple comparisons problem

I promised I wouldn’t do any new blogging until January but I’m here at this conference and someone asked me a question about the above slide from my talk. The point of the story in that slide is that flat priors consistently give bad inferences. Or, to put it another way, the routine use of […] The post Bayesian inference completely solves the multiple comparisons problem appeared first on Statistical…

Create an animation with the BY statement in PROC SGPLOT

It is easy to use PROC SGPLOT and BY-group processing to create an animated graph in SAS 9.4. Sanjay Matange previously discussed how to create an animated plot in SAS 9.4, but he used a macro loop to call PROC SGPLOT many times. It is often easier to use the […] The post Create an animation with the BY statement in PROC SGPLOT appeared first on The DO Loop.

Things that sound good but aren’t quite right: Art and research edition

There are a lot of things you can say that sound very sensible but, upon reflection, are missing something. For example consider this blog comment from Chris G: Years ago I heard someone suggest these three questions for assessing a work of art: 1. What was the artist attempting to do? 2. Were they successful? […] The post Things that sound good but aren’t quite right: Art and research edition…

When testing trading strategies a common approach is to divide the initial data set into in sample data: the part of the data designed to calibrate the model and out of sample data: the part of the data used to validate the calibration and ensure that the performance created in sample will be reflected in the […]

GMO labeling is good science

August 18, 2016
By

A GMO labeling law has arrived in the US, albeit one that has no teeth (link). For those who don't want to click on the link, the law is passed in haste to pre-empt a more stringent Vermont law. The federal law defines GMO narrowly, businesses do not need to put word labels on packages (they can, for example, provide an 800-number), and violaters will not be punished. One of…

My criticism of R numeric summary

My criticism of R‘s numeric summary() method is: it is unfaithful to numeric arguments (due to bad default behavior) and frankly it should be considered unreliable. It is likely the way it is for historic and compatibility reasons, but in my opinion it does not currently represent a desirable set of tradeoffs. summary() likely represents … Continue reading My criticism of R numeric summary

Two Ideas for a Better Visualization Web

There is a reasonable amount of information about visualization available on the web. There are still huge gaps though, especially when it comes to bridging the gap between academic research and the rest of the world, though. Here are two ideas: one simple, one rather involved.
