statsthinking21-core's Issues

Chapter 6 Fixes

Just noticed that "A real-world example of this was seen in the 2017 special election for the US Senate in Georgia, which pitted the Republican Roy Moore against Democrat Doug Jones.", should be for Alabama rather than Georgia. Thanks for the great refresher book!

Chapter 12 Table 12.1 - Rounding Issue

I can't replicate this locally with knitr (I get 33.33 for nullExpectation) but the book site has a confusing rounding (below). Not really a big deal but took me a second glance.

From the book site:

Amazing book and collection of further readings - thank you for putting this online.

Chapter 6 small error on sensitivity

In the "6.8 Learning from data" section, sensitivity is referred to as

the probability of cancer given a positive test outcome

It should be "the probability of a positive test outcome given cancer is present", i.e., $P(test|cancer)$.

validity of HG Well quotation

from Ralf Valerian:
wrt to
The H.G. Wells Quote on Statistics: A Question of Accuracy
by James W. Tankard, Jr.,
The University of Texas at Austin, Austin, TX 78712
Historia Mathematics 6 (1979), 30-33
https://core.ac.uk/download/pdf/82336451.pdf

Wells passage in "Mankind in the making"
seems to me much closer to your focus of "statistical thinking"
"to describe the world accurately" than the "quote"

link in preface points to old repo

Hi @poldrack

Very minor issue and you might be aware of this already but I just noticed this link in the preface still points to the old repo

This book is meant to be a living document, which is why its source is available online at [https://github.com/poldrack/psych10-book](https://github.com/poldrack/psych10-book). If you find any errors in the book or want to make a suggestion for how to improve it, please open an issue on the Github site. Even better, submit a pull request with your suggested change.

(Guessing you want it to point here instead)

incorrect PPV value

From Itamar Giladi:

As I was planning to demonstrate the PPV concept following your (and Ionnidis) example, I found that the PPV for the second case in section 18.3.1. should be 0.64 rather than 0.307.

minor issues

by email:

• When referring to Figure 6.2 (probability table), you call the red cells "light blue".
• The probability that Steph Curry makes 4 out of 4 is surely not 1.00 (as shown in Table 6.1) but rather about 65% (1 - the probability of him making 3,2,1, or 0)

Translation to Spanish

We've translated the book to Spanish (MX), but I'm unsure of how best to share it. I've uploaded into a private github repository for now: would it be best to share it publicly from there?
