In 2001, I was fortunate to discover a ‘market characteristic’ that transcends virtually every liquid market. Markets often trend in a nonlinear fashion according to hidden support/resistance curves (Stealth Curves).  Whereas ‘market anomalies’ are transient and are overwhelmingly market specific, Stealth Curves are highly robust across virtually every market and ...

Parallel processing in the tidyverse couldn’t be easier with the furrr package. If you are familiar with the purrr::map() function, then you’ll love furrr::future_map(), which we’ll use in this FREE R-Tip training to get a 2.6X speed-up in our code. R...

In the previous post, I simulated data from a hypothetical RCT that had heterogeneous treatment effects across subgroups defined by three covariates. I presented two Bayesian models, a strongly pooled model and an unpooled version, that could be us...

Progress bar showing the number of days until end of the year. Yes, only based on the days and not hour. And needless to say, the progress is soothing using ASCII charts. So the function is fair to say, simple…Read more ›

Bond duration is the first order linear approximation and thus does not consider a non-linearity. Making up for this shortcoming of the duration, a convexity is needed to describe the non-linearity of a bond price. This post explains the meaning and c...

For a long time I have wondered why some people would use position_stack() for position alignment instead of the simpler version position = "stack". Recently, though, I learned the purpose of the former approach when I tried to add data label...

While R has variety of options to choose from when it comes to 2D graphics and data visualisation, it is hard to beat ggplot2 in terms of features, functionality and overall visual quality. I wanted to share my take on how to use the package which is, ...
