The diffogram and other graphs for multiple comparisons of means

In a previous article, I discussed the lines plot for multiple comparisons of means. Another graph that is frequently used for multiple comparisons is the diffogram, which indicates whether the pairwise differences between means of groups are statistically significant. This article discusses how to interpret a diffogram. Two related plots [...] The post The diffogram and other graphs for multiple comparisons of means appeared first on The DO Loop.

Graphs for multiple comparisons of means: The lines plot

Last week Warren Kuhfeld wrote about a graph called the "lines plot" that is produced by SAS/STAT procedures in SAS 9.4M5. (Notice that the "lines plot" has an 's'; it is not a line plot!) The lines plot is produced as part of an analysis that performs multiple comparisons of [...] The post Graphs for multiple comparisons of means: The lines plot appeared first on The DO Loop.

Create and interpret a weighted histogram

If you perform a weighted statistical analysis, it can be useful to produce a statistical graph that also incorporates the weights. This article shows how to construct and interpret a weighted histogram in SAS. How to construct a weighted histogram Before constructing a weighted histogram, let's review the construction of [...] The post Create and interpret a weighted histogram appeared first on The DO Loop.

Some ideas on using virtual reality for data visualization:  I don’t really agree with the details here but it’s all worth discussing

Evan Warfel writes: Misleading graphs are one thing you consistently write about, and it seems to me that Virtual Reality has the potential to solve part of this problem — there is no point in sharing a “static” VR experience; instead, by allowing users to change the axes and interact with the data, they have […] The post Some ideas on using virtual reality for data visualization: I don’t really…

I’m on the program committee and they say they’re looking to broaden their horizons this year to include systems like Stan. The workshop is part of POPL, the big programming language theory conference. Here’s the official link PPS 2018 home page Call for extended abstracts (2 pages) The submissions are two-page extended abstracts and the […] The post Call for papers: Probabilistic Programming Languages, Semantics, and Systems (PPS 2018) appeared…

(This is not a paper we wrote by mistake.) (This is also not Andrew) (This is also really a blog about an aspect of the paper, which mostly focusses on issues around visualisation and how visualisation can improve workflow. So you should read it.) Recently Australians have been living through a predictably ugly debate around […] The post Touch me, I want to feel your data. appeared first on Statistical…

Stan Weekly Roundup, 25 August 2017

This week, the entire Columbia portion of the Stan team is out of the office and we didn’t have an in-person/online meeting this Thursday. Mitzi and I are on vacation, and everyone else is either teaching, TA-ing, or attending the Stan course. Luckily for this report, there’s been some great activity out of the meeting […] The post Stan Weekly Roundup, 25 August 2017 appeared first on Statistical Modeling, Causal…

Cumulative residual plots seem like they could be useful

August 23, 2017
By

Peter Vanney, a statistician at Texas Highway Patrol, writes: I’m wondering if you could comment on CURE (CUmulative REsidual) plots that I’m seeing quite a bit in vehicle crash modeling. Ezra Hauer and Joseph Bamfo champion them as a way to determine model fit for their hierarchical Bayesian generalized linear mixed models. I had not […] The post Cumulative residual plots seem like they could be useful appeared first on…
