The short course focuses on programming algorithms in NIMBLE ...

TL; DR  I used a Kaggle database to show you how to separate your customers into distinct groups based on their purchase behavior.  With this method, store managers can customize interactions with  existing and potential customers to increase loyalty and eventually, all of the goodies that come with consistent purchases.  ...

Testing for interactions in nonlinear regression Factorial experiments are very common in agriculture and they are usually laid down to test for the significance of interactions between experimental factors. For example, genotype assessments may b...

Testing for interactions in nonlinear regression Factorial experiments are very common in agriculture and they are usually laid down to test for the significance of interactions between experimental factors. For example, genotype assessments may be performed at two different nitrogen fertilisation levels (e.g. high and low) to understand whether ...

Accounting for the experimental design in regression analyses In this post, I am not going to talk about real complex models. However, I am going to talk about models that are often overlooked by agronomists and biologists, while they may be necessary in several circumstances, especially with field experiments. The ...
