Working Up

by Dwayne Phillips These inconvenient facts seem to be everywhere. They are inconvenient, however, only when we have a story to tell that denies reality. There are some old sayings like, “opinions being mugged by facts,” and “don’t confuse my opinion with facts,” and “there is nothing like facts getting in the way of my […]

by Dwayne Phillips Measuring small things is much more difficult than measuring large things. We do it anyways and report the results with great confidence. Woe is us. It is more difficult to measure small things that it is to measure large things. Consider measuring the diameter of a sphere. We can use a device […]

by Dwayne Phillips We have more data today. Really? I don’t think so. We do have more places to put data, so we need to put something there. Right? I don’t know how many times I have read about all the new data we have today. The amount of data we have is BIG. The […]

Sometimes neither work. Data is everywhere. Data is the new oil or bacon or pizza or something good or bad. The trouble with data is if I […]

by Dwayne Phillips Lest we forget, we have always had more data than we could process. For some reason, we are now recording it with magnetism. I just read yet another article telling me that “data is everywhere.” Then there are the usual numbers of peta-peta-something-or-other bytes of data every second or so. Cries follow […]

by Dwayne Phillips Linear Regression is an old, basic technique to predict the future given the past. It seems that its utility has been forgotten by many. How did we get here? Why didn’t anyone see this coming? These are a couple questions I heard recently when groups of persons gathered to discuss … well, […]

by Dwayne Phillips This is a variation on the question, “What is the difference that makes a difference?” When trying to modify behavior, we must be able to answer the title’s question. The title of this post is a fundamental science question. You are telling me that factor A is important here. Okay, it seems […]
