Missed Friday the 13th Zombie Plot Update

The revised paper plot13.pdf Slightly improved figures figure13.pdf And just the history part from my thesis – that some find interesting. (And to provide a selfish wiki meta-analysis entry pointer) JustHistory.pdf I have had about a dozen friends read this or earlier versions – they split into finding it interesting (and pragmatic) versus incomprehensible. The […]

Explaining that plot.

With some upgrades from a previous post. And with a hopefully clear 40+ page draft paper (see page 16). Drawing Inference – Literally and by Individual Contribution.pdf Comments are welcome, though my reponses may be delayed. (Working on how to best render the graphs.) K? p.s. Plot was modified so that it might be better […]

What Zombies see in Scatterplots

This video caught my interest – news video clip (from this post2) http://www.stat.columbia.edu/~cook/movabletype/archives/2011/02/on_summarizing.html The news commentator did seem to be trying to point out what a couple of states had to say about the claimed relationship – almost on their own. Some methods have been worked out for zombies to do just this! So I […]

Attractive models (and data) wanted for statistical art show.

I have agreed to do a local art exhibition in February. An excuse to think about form, colour and style for plotting almost individual observation likelihoods – while invoking the artists privilege of refusing to give interpretations of their own work. In order to make it possibly less dry I’ll try to use intuitive suggestive […]

Biostatistics via Pragmatic and Perceptive Bayes.

This conference touches nicely on many of the more Biostatistics related topics that have come up on this blog from a pragmatic and perceptive Bayesian perspective. Fourth Annual Bayesian Biostatistics Conference Including the star of that recent Cochrane TV debate who will be the key note speaker. See here Subtle statistical issues to be debated […]

Subtle statistical issues to be debated on TV.

There is live debate that will available this week for those that might be interested. The topic: Can early stopped trials result in misleading results of systematic reviews?

Course proposal: Bayesian and advanced likelihood statistical methods for zombies.

The course outline ZombieCourseOutline.rtf Hints/draft R code for implementing this for a regression example from D. Pena x=c(1:10,17,17,17) y=c(1:10,25,25,25) ZombieAssign1.txt The assignment being to provide a legend that explains all the lines and symbols in this plot ZombieAssign1.pdf With a bonus assignment being to provide better R code and or techniques. And a possible graduate […]

UnConMax – uncertainty consideration maxims 7 +/- 2

Warning – this blog post is meant to encourage some loose, fuzzy and possibly distracting thoughts about the practice of statistics in research endeavours. There maybe spelling and grammatical errors as well as a lack of proper sentence structure. It may not be understandable to many or even possibly any readers. But somewhat more seriously, […]

Should Mister P be allowed/encouraged to reside in counter-factual populations?

Lets say you are repeatedly going to recieve unselected sets of well done RCTs on various say medical treatments. One reasonable assumption with all of these treatments is that they are monotonic – either helpful or harmful for all. The treatment effect will (as always) vary for subgroups in the population – these will not […]

Zombie student manipulation of symbols/taking of course notes

As with those who manipulate symbols without reflective thought, that Andrew raised, I was recently thinking abouts students who avoid any distraction that might arise by their thinking about what the lecturer is talking about – so that they are sure to get the notes just right. When I was a student I would sometimes […]
