It is intriguing that you remark on my vendors having me well-trained. Let's make sure that we have full disclosure for readers here on background and connections to vendors.
I am currently employed as General Manager of Analytics at LinguaSys, a software vendor specialized in language processing such as text analytics, including Big Data applications. In the past, I have been an independent analytics consultant (and continue to do a limited amount of consulting), an in-house statistician and an engineer (not a software engineer, a pipes, valves and steam engineer). For many years, I was employed at another software vendor, SPSS, which has since been acquired by IBM. In addition to the products developed by my employers, I have used a variety of other statistical analysis tools.
My training in sampling methods came not from any vendor, but from a university. I completed around a dozen classes in statistical theory and applications as part of my training for a BS in mathematics, and later expanded on that while earning a Masters in Engineering. This training was not heavily influenced by software vendors as academics rarely touched software in those days. It was done the old fashioned way with detailed discussion of theorems, derivation of proofs, and lots of manual calculations. Other than the occasional use of a hand calculator, we did not use automated computing for statistics at all.
Now, Paige, would you care to make similar disclosures about your own loyalties and training?
My current and past employers could sometimes make a heap more money in the short term if I advised prospective customers to do things your way. I'm proud to say that no employer of mine has ever encouraged such behavior. They don't encourage it because they are smart enough to know that there are better strategies for the customer, and that it's good business to offer solid, cost-effective, long-term solutions.
