War by Numbers
just arrived. With a whole chapter based on the Italian engagements.
I happen to be reading this book: I cannot believe how poor this is. It's really sub-level in terms of statistics, with such gross limitations it is almost unbelievable the author takes his work seriously.
I'm just 9 chapters in the book but here's what I see:
- the most advanced statistical tool is the average. Standard deviation is beyond the ability of the author. (Therefore Lawrence routinely compares averages of 2 series without ever asking whether the difference is large enough to have statistical significance)
(and there is one in-text standard deviation but it is larger than the average!)
- plotting 2 variables on a chart and drawing conclusions without calculating a linear regression R2... Someone's got to show him the excel button to have it automatic...
Every page it says "I take myself seriously but I do not master high-school mathematics".
And I'm not even talking of statistical tests like chi-square etc.
