This book does an excellent job of facilitating self-study of the math underpinning multivariate statistical analysis ... namely, linear (matrix) algebra and some calculus. Each chapter has a set of questions and ALL of the answers are provided in the book (handy for self-study). The one slight critique of this book I can give is that I wish the book did more on the calculus aspects. However, that is a minor comment and the knowledge that this book imparts of linear algebra to self-learners is extremely valuable.

From what I learned during the late 70's and early 80's while working with Naval Officers, both books are authentic, especially in the attitudes reflected by the military. For people who want to understand the Vietnam war and the effect of the civilian leadership on the military during this time, I strongly encourage you to read both books.
Thank you Sir.
Page 20 says IBM developed "a lush bureaucracy that prided itself on having a higher ratio of managers per employee than any other business around." Is this what they teach in business school? IBM's chairmen came from the sales force; if you can't sell it, there's no point in making it. The IBM PC was created from off-the-shelf parts so it could be quickly marketed; pre-defined interfaces too! Page 24 tells how Microsoft did an operating system: they licensed QDOS (a replica of CP/M), then bought it. It eventually made Gates the richest man in America.
Page 27 tells of the management problem in creating software. Architects spent months producing detailed designs for software. Then masses of programmers had a hard time deciphering the hundreds of pages of specifications. More time was spent in communicating than actually writing code! Isn't this a recipe for a project to be over budget and behind schedule? Estridge's habit of shunning meetings, not returning phone call, and ignoring unwanted advice could set an example of a well-ordered project manager who concentrates on the mission, not the housekeeping. Page 37 explains why standards for PCs began at birth.
Page 53 mentions the "fear of nuclear attack" as the reason for moving out of New York city. But other companies also moved out in the 1970s; the fear of a nuclear attack drained away after the Cuban Missile Crisis of 1962. Didn't IBM build a skyscraper in the 1980s only to sell it in the 1990s? Didn't AT&T do the same?
Page 87 tells how Gates got lucky when VisiCorp began to self-destruct. Those familiar with counter-intelligence operations may think of another reason (p.192). Page 97 says IBM never wanted to have too many people in one spot. Unstated here is the fear that nearly all could walk out to a new company (p.186). Page 101 tells that IBM used lines of code as a measure of programming; what did IBM use to measure its management? Microsoft rewrote IBM code to make it faster and smaller, then; how are they doing now? The last pages of Chapter 8 deal with the OS/2-Windows politics. There is no explanation as to why they didn't share the same application interface. Page 201 tells of developing a RISC chip; didn't CDC do this in the early 1960s? Page 208 describes the chip development problem in Burlington VT. Page 217 mentions the "golden screwdriver" and how quickly some machines were upgraded. Think ahead!
Pages 245-7 tell of the PS/1 project: crippled so it would not compete with PS/2. Would General Motors restrict the sale of Chevrolets to sell more Cadillacs? Page 281 suggests Microsoft moles reported on IBM's strategies. Pages 301-9 tell of the changes in Lexington under new owners. In political history, this is like a revolution that sweeps away the aristocracy and lets the farmers and merchants rise to power. Does the description of the IBM bureaucracy remind you of France before the Revolution? Will anyone write a book to cover the last ten years as well as this one does?
Luckily, IBM has pulled itself out, but at what cost? Imagine if IBM had got the PC revolution right? There might not even be a Microsoft today and IBM could have retaken its position as THE corporate super-power.
Besides discussing poor management, I enjoyed the information and great anecdotes about IBM's relationship with Bill Gates and Microsoft. I cannot believe the number of opportunities IBM squandered to acquire, invest or eliminate Microsoft. It seems that IBM pratically pushed Gates to build Microsoft into the power it is today.
