Crisis from the South /3

The Inter-American Development Bank publishes today on its web-site previsions for remittance flows in 2009 to Latin America: they will go down for the first time since 2000. And different countries are experiencing different situation. The Andean region is effected worse by the decline of the euro whereas the Mesoamerica region sees a strong dollar partially counterbalance the decrease in money flow.

According to the Banco de Guatemala, in the first two month of 2009 remittances to the country have diminished by 9.59% comparing with same period of 2008.

  • Monitoring Website SSL/TLS Certificate Expiration Times with R, {openssl}, {pushoverr}, and {DT}
    macOS R users who tend to work on the bleeding edge likely noticed some downtime at this past weekend. Part of the issue was an SSL/TLS certificate expiration situation. Moving forward, we can monitor this with R using the super spiffy {openssl} and {pushoverr} packages whilst also generating a daily report with {rmarkdown} and... Continue […]
  • Evaluate your R model with MLmetrics
    This post will explore using R’s MLmetrics to evaluate machine learning models. MLmetrics provides several functions to calculate common metrics for ML models, including AUC, precision, recall, accuracy, etc. Building an example model Firstly, we need to build a model to use as an example. For this post, we’ll be using a dataset on pulsar […]
  • Data re-Shaping in R and in Python
    Nina Zumel and I have a two new tutorials on fluid data wrangling/shaping. They are written in a parallel structure, with the R version of the tutorial being almost identical to the Python version of the tutorial. This reflects our opinion on the “which is better for data science R or Python?” They both are […]
  • Does Australia need More Fires (but the Right Kind)? A Multi-Agent Simulation
    We have all watched with great horror the catastrophic fires in Australia. Over many years scientists have been studying simulations to understand the underlying dynamics better. They tell us, that “what Australia needs is more fires, but of the right kind”. What do they mean by that? One such simulation of fire is based on […]
  • Some everyday data tasks: a few hints with R (revisited)
    One year ago, I published a post titled ‘Some everyday data tasks: a few hints with R’. In that post, I considered four data tasks, that we all need to accomplish daily, i.e. subsetting sorting casting melting In that post, I used the methods I was more familiar with. And, as a long-time R user, […]

  • You can replicate almost any plot with R
    Although R is great for quickly turning data into plots, it is not widely used for making publication ready figures. But, with enough tinkering you can make almost any plot in R. For examples check out the flowingdata blog or the Fundamentals of Data Visualization book. Here I show five charts from the lay press […]
  • So You Want to Start a Podcast
    Podcasting has gotten quite a bit easier over the past 10 years, due in part to improvements to hardware and software. I wrote about both how I edit and record both of my podcasts about 2 years ago and, while not much has changed since then, I thought it might be helpful if I organized […]

  • Are GWAS studies of IQ/educational attainment problematic?
    Nick Matzke writes: I wonder if you or your blog-colleagues would be interested in giving a quick blog take on the recent studies that do GWAS (Genome-Wide-Association Studies) on “traits” like IQ, educational attainment, and income? Matzke begins with some background: The new method for these studies is to claim that a “polygenic score” can […]
  • Causal inference in AI: Expressing potential outcomes in a graphical-modeling framework that can be fit using Stan
    David Rohde writes: We have been working on an idea that attempts to combine ideas from Bayesian approaches to causality developed by you and your collaborators with Pearl’s do calculus. The core idea is simple, but we think powerful and allows some problems previously that only had known solutions with the do calculus to be […]
  • My review of Ian Stewart’s review of my review of his book
    A few months ago I was asked to review Do Dice Play God?, the latest book by mathematician and mathematics writer Ian Stewart. Here are some excerpts from my review: My favorite aspect of the book is the connections it makes in a sweeping voyage from familiar (to me) paradoxes, through modeling in human affairs, […]
