Running into errors and warnings is a completely normal part of programming – even the best of the best can count on it happening daily! Getting comfortable with what the errors mean and how to find the solution is part of your learning journey. Here’s a checklist (pdf /png) with … ...

The collection of R books at BigBookofR continues to grow! Thanks to @erictleaungu , @StanLazic, @rohmanoabdur, @preposterior, @lago67522285 and @lfvasconcelos_ for their contributions. Computing for the social sciences By Dr. Benjamin Soltoff The goal of this course is to teach you basic computational skills and provide you with the means … The ...

The duration of a floating rate note (FRN) is the remaining time until the first next payment date. Using this fact, a duration of FRN has not been calculated explicitly but has been understood conceptually. Instead of this reasoning, this post trie...

I love the clean simplicity of an R Markdown document. But sometimes it can feel a little bare and utilitarian. This is especially the case if it’s rendered into the body of an email. How about injecting a little more pizzazz? library(emayili) Check on the installed version. packageVersion("...

One of the main assumptions of linear regression taught in statistics courses is that of “constant variance” or “homoscedasticity.” Having data that do not have constant variance (i.e., are heteroscedastic) is then often treated as a problem—a nuisance that violates our assumptions and, among other things, produces inaccurate ...

The IPL 2021 extravaganza has restarted again, now in Dubai, and it was time for me to crank up good ol’ GooglyPlusPlus2021. As in my earlier post, GooglyPlus2021 with IPL 2021 as it happens, during the initial set of IPL 2021 games,, a command script will execute automatically every day, download the latest ...

Have you ever spent the whole day applying different Machine Learning (ML) algorithms from several libraries, coping with a legion of conditional and unconditional hyperparameters, and attempting to deal with different data processing techniques? Undeniably, it is a try-and-error work with prerequisite experience. These repeatable trials can be very time-consuming ...

The price of a floating rate bond is always equal to the face value at the payment dates and the duration is the remaining time until the first next reset date. This post explains these arguments by using some heuristic derivations and R code. F...
