Classical statistics VS Bayesian statistics Ning Tian September 4, 2017 The main di erence between the two statistics is that the former regards unknown, and the latter regards as a random variable having an unknown distribution. Analysis Procedures". Inferences about regionally specific effects are based on the ensuing image of T statistics, the SPM{T}. Photo by the author. 6.1 Subjectivity. On the other hand progess in applications is being seen by making priors more wrong (weakly informative) rather than less wrong …. I didn’t think so. Another example I use early on is this one: I ask, about mammograms (the numbers are about right), suppose a woman has a mammogram. To Since my background and training are in the physical sciences, I've noticed that all but the most sophisticated of my colleagues (that is, those that have learned enough statistics to be dangerous :0), think that a confidence interval is a credible interval. However, there are Bayesian functions in various software packages that appear to work like the typical frequentist procedure, so this is not always an issue. David MacKay [2] also has some excellent references. My conclusion is that, in certain situations, they cannot. I then look at the coin without letting anyone else see it. One problem with finding statistical resources on the web, I think, is that a webpage on a technical issue is likely to have been written by a computer scientist. They are still thinking as Bayesians (their background information is different from mine, and they are, perhaps unconsciously, conditioning on the data they have). It is surprising to most people that there could be anything remotely controversial about statistical analysis. In appraising statistical accounts at the foundational level, we need to realize the extent to which accounts are viewed through the eyeholes of a mask or philosophical theory. We hope this comparison has thrown at least some light on the fundamental difference between the Classical and Bayesian approaches to statistical analysis, a difference that continues to divide the statistical community and provides a continuing source of controversy, debate and interest in the field of statistics.

Because in so many practical circumstances the statements look the same, econometricians are often not careful about the diﬀerent meanings, or even not too sure what the diﬀerences are. The Jaynes and MacKay books are excellent, but from a statistical perspective, I prefer chapter 1 of Bayesian Data Analysis. Based on this, other comments in the book and other writings of Gigerenzer, it is my strong impression that he is a Frequentist and there is little about Bayesian thinking in his writing. 1. Those that say 0.5 are thinking as Bayesians; the others are thinking as frequentists. Though Classical statistics can be somewhat “clunky” in answering real questions, it is objective and therefore dependable. https://www.quantstart.com/articles/Bayesian-Statistics-A-Beginners-Guide for(j=0;j
