When I arrived in the REA department at Saint Paul Public Schools, the report generation process was roughly as follows: 1. Do the analysis in SPSS...

When working with intraday data, analysts are often facing a large dataset problem. R is well equipped to deal with this but the standard approach has to be modified in some ways. Large dataset means different things to different people. I’m talking here about a dataset of less than 10 columns and 2 to 5

Munkres’ Assignment Algorithm (Munkres (1957), also known as hungarian algorithm) is a well known algorithm in Operations Research solving the problem to optimally assign N jobs to N workers. I needed to solve the Minimal Assignment Problem for a relabeling algorithm in MCMC sampling for finite mixture distributions, where I use a random permutation Gibbs sampler. For each sample...

Date and time handling is essential to many modelling and analysis exercises, in R and other languages used for scientific computing. Over the past few months I tackled the mapping of date-time concepts between R and the .NET framework as part of the w...
