colourpicker package v1.0: You can now select semi-transparent colours in R (& more!)
For those who aren’t familiar with the colourpicker package, it provides a colour picker for R that can be used in Shiny, as well as other related tools. Today it’s...continue reading.
Weird Al Yankovise() a 2 Chainz Lyric
I have a character string snipped from a lyric by Daniel Son the Necklace Don. Let’s get all Weird Al Yankovic with it. I’ll revise some words with the datzen::yankovise()...continue reading.
The BayesianTools R package with general-purpose MCMC and SMC samplers for Bayesian statistics
This is a somewhat belated introduction of a package that we published on CRAN at the beginning of the year already, but I hadn’t found the time to blog about this earlier....continue reading.
Get out of my way! Dunk thru #rstats errors like the Big Shaq-istician
Ahh, leaves falling, parents crying, collegicians biking uphill with a bag of in-n-out in between their teeth. Must be the new academic school year! I figured it’s a good time...continue reading.
Last Day for Stanton Predictions
This week I’ve been looking at two models in R that are attempting to predict whether Giancarlo Stanton would break Roger Maris’ mark of 61 home runs in a season....continue reading.
Monotonic WoE Binning for LGD Models
While the monotonic binning algorithm has been widely used in scorecard and PD model (Probability of Default) developments, the similar idea can be generalized to LGD (Loss Given Default) models....continue reading.
Hold the Phones . . . Stanton’s Alive Again
Sometimes, events move faster than we predict them. This is one of the things that makes statistics as much of an art as a science. Last night, Giancarlo Stanton hit...continue reading.
Going, Going . . . 1
Two posts today with similar themes. Time is running out. First, time is running out for Giancarlo Stanton. His bat has been very silent this week so far. The Marlins...continue reading.
Microsoft Cognitive Services Vision API in R
Microsoft Cognitive Services Vision API in R A little while ago I did a brief tutorial of the Google Vision API using RoogleVision created by Mark Edmonson. I couldn’t find...continue reading.
The Battle of Bayesian Home Run Models
The regular Major League Baseball season is coming to an end. Next week, we move into the playoffs and eventually the World Series. However, we have a nice statistical modeling...continue reading.
Granular Monotonic Binning in SAS
In the post (https://statcompute.wordpress.com/2017/06/15/finer-monotonic-binning-based-on-isotonic-regression), it is shown how to do a finer monotonic binning with isotonic regression in R. Below is a SAS macro implementing the monotonic binning with the...continue reading.
Exploratory Data Analysis of Tropical Storms in R
Exploratory Data Analysis of Tropical Storms in R The disastrous impact of recent hurricanes, Harvey and Irma, generated a large influx of data within the online community. I was curious...continue reading.
Model Non-Negative Numeric Outcomes with Zeros
As mentioned in the previous post (https://statcompute.wordpress.com/2017/06/29/model-operational-loss-directly-with-tweedie-glm/), we often need to model non-negative numeric outcomes with zeros in the operational loss model development. Tweedie GLM provides a convenient interface to...continue reading.
Mathpy 0.3.0 Released!
I am excited to announce the release of mathpy 0.3.0! This release adds a ton of Excel UDFs including many new statistical and number-theoretic functions, several random number generators and…...continue reading.
Blocked Gibbs Sampling in R for Bayesian Multiple Linear Regression
In a previous post, I derived and coded a Gibbs sampler in R for estimating a simple linear regression. In this post, I will do the same for multivariate linear...continue reading.
Variable Selection with Elastic Net
LASSO has been a popular algorithm for the variable selection and extremely effective with high-dimension data. However, it often tends to “over-regularize” a model that might be overly compact and...continue reading.
Pair Programming Statistical Analyses
Abstract Control calculation ping-pong is the process of iteratively improving a statistical analysis by comparing results from two independent analysis approaches until agreement. We use the daff package to simplify...continue reading.
