I am happy to announce the release of ICC Bot, an app for computing interrater reliability scores using the intraclass correlation coefficient (ICC). A screenshot of ICC Bot, an interactive app for computing intraclass correlation coefficients. The ICC statistic appears in repeated measures or multilevel modeling literature as a way ...

I’ve never really worked much with Poisson data and wanted to get my hands dirty. I thought that for this project I might combine a Poisson data set with the simple Bayesian methods that I’ve explored before since it turns out the Poisson rate parameter lambda also has ...

Another low-key arithmetic problem as Le Monde current mathematical puzzle: Notice that there are 10 numbers less than, and prime with 11, 100 less than and prime with 101, 1000 less than, and prime with 1111? What is the smallest integer N such that the cardinal of the set of M

The nature of work today requires continuous learning and the ability to respond appropriately to new information—including an increasing abundance of data. Companies must ensure that their employees are data fluent—those that do outperform their ...

India is the world’s largest Democracy and as it goes, also a highly diverse place. This is my attempt to see how “Hindi” and other languages are spoken in India. In this post, we’ll see how to collect data for this relevant puzzle - directly from Wikipedia and ...

Advances in microfluidic technologies enabled us to barcode single cells in lipid droplets and to resolve genomes of individual cells from a sequencing mixture (e.g, 10X Genomics). By using Single cell RNA sequencing (scRNA-seq) we can discover rare cell populations and genes that are specifically acting in those. Potential ...

easyalluvial allows you to build exploratory alluvial plots (sankey diagrams) with a single line of code while automatically binning numerical variables. This releas 0.2.1 ensures tidyr 1.0.0 compatibility and fixes a bug around categorical variables for model response plots Model Response Plots with Categorical Variables This feature had som glitches before as ...

In a current multi-site study, we are using a stepped-wedge design to evaluate whether improved training and protocols can reduce prescriptions of anti-psychotic medication for home hospice care patients with advanced dementia. The study is officially called the Hospice Advanced Dementia Symptom Management and Quality of Life (HAS-QOL) Stepped Wedge ...

R is in an increasingly popular language for data analysis and data science. Here's how you can learn R and be sure it sticks so you can get the career you want. The post Learn R the Right Way in 5 Steps appeared first on Dataquest.

The modern business world is captivated by data science and analytics. It seems like in almost every enterprise there is talk of needing to bulk up the data science and analytics functions to solve all conceivable business problems and chart the company towards endless success. In more cash-rich operations, management ...

In my last post, I showed how the feasts package can be used to produce various time series graphics. The feasts package also includes functions for computing FEatures And Statistics from Time Series (hence the name). In this post I will give three examples of how these might be used. {{...

A low-key sorting problem as Le Monde current mathematical puzzle: If the numbers from 1 to 67 are randomly permuted and if the sorting algorithm consists in picking a number i with a position higher than its rank i and moving it at the correct i-th position, what is the maximal number ...
