Introduction As discussed in the previous post, I’ve recently constructed and delivered a short course on statistical computing with Scala. Much of the course is concerned with writing statistical algorithms in Scala, typically making use of the scientific and numerical computing library, Breeze. Breeze has all of the essential tools necessary for building statistical algorithms, … Continue reading scala-glm: Regression modelling in Scala
I’ve recently delivered a three-day intensive short-course on Scala for statistical computing and data science. The course seemed to go well, and the experience has convinced me that Scala should be used a lot more by statisticians and data scientists for a range of problems in statistical computing. In particular, the simplicity of writing fast … Continue reading Statistical computing with Scala free on-line course
Tomorrow, around noon, I will be giving a talk on predictive modeling for actuaries. In the introduction, I will get back shortly on the idea that a prediction is usually a best estimate, in the sense of getting an expected value. And because it is natural to use least square ideas. In order to illustrate all those concepts, we will use a simple dataset, with the sex, the height and…
I will give, with Qichun Xu, a joint webinar for the Reinsurance Council and the Futurism Council of the Society of Actuaries, on Perspectives of Predictive Modeling with Case Studies in a few days. The slides of my talk are now available (I do recommand to open the pdf version of the slides with Acrobat, since there are animated pictures in the slides that could not be visualized below for instance).…
Let’s say you are in the middle of a salary negotiation, and you want to know whether you should be aggressive in your offering or conservative. One way to help with the decision is to make a decision tree. We’ll work with the following assumptions...
