In this post I compare GISS LOTAs during 5 El Nino – La Nina cycles (2010, 1998, 19883, 1973 and 1970). El Nino – La Nina Cycles In a previous post I showed the Nino 34 SSTA cycles for 2010, … Continue reading →

Comparison of GISS LOTAs During 5 El Nino – La Nina Cycles
Comparing two-dimensional data sets in R; take II
David commented on yesterday's post and suggested to put the continuous fitted distribution in the background and the discrete, empirical distribution in the foreground. This looks quite nice, although there's a slight optical illusion that makes the c...

In case you missed it: February Roundup
In case you missed them, here are some articles from February of particular interest to R users. Revolution R Enterprise 4.2 is now available to subscribers, and for free download to academics. A brief report from the Strata: Working with Data conference, and a comprehensive review from Ted Leung. A profile of prolific R contributor, Dirk Eddelbuettel. A list...
Comparing two-dimensional data sets in R
I wanted to fit a continuous function to a discrete 2D distribution in R. I managed to do this by using nls, and wanted to display the data. I discovered a nice way to compare the actual data and the fit using ggplot2, where the background is the real ...

Forest plots using R and ggplot2
Abhijit over at Stat Bandit posted some nice code for making forest plots using ggplot2 in R. You see these lots of times in meta-analyses, or as seen in the BioVU demonstration paper. The idea is simple - on the x-axis you have the odds ratio (or what...
Splitting a Dataset Revisited: Keeping Covariates Balanced Between Splits
In my previous post I showed you how to randomly split up a dataset into training and testing datasets. (Thanks to all those who emailed me or left comments letting me know that this could be done using other means. As things go with R, it's sometimes ...
Our Friend the Age-Earnings Profile
I like Labor Economics. Partially because it has a nice mix of theory and practical empiricism, but mostly because it seems to be a sub-field with a number of agreed upon stylized facts that grow not out of micro theory … Continue reading →
Example 8.29: Risk ratios and odds ratios
When can you safely think of an odds ratio as being similar to a risk ratio?Many people find odds ratios hard to interpret, and thus would prefer to have risk ratios. In response to this, you can find several papers that purport to convert an odds rat...
