Why People Are Doubting the AstraZeneca Vaccine Report
In this blog post, I use Gelman and Loken’s garden of forking paths analysis to construct a simulation showing why skepticism of AstraZeneca’s vaccine results is warranted at this early stage. This simulation uses the numbers from their press relea... [Read more...]
A Mini MacroEconometer for the Good, the Bad and the Ugly
Gross domestic product (GDP) is the total monetary or market value of all the finished goods and services produced within a country's/state’s borders in a specific time period. As a broad measure of overall domestic production, it functions as a comprehensive scorecard of a given country’s/state’...
Custom Google Analytics Dashboards with R: Downloading Data
This week, I’m taking a break from our regular blog content to write about some of the nitty-gritty data science we do within RStudio. Specifically, I’m going to address a question I was asked soon after joining the blogging team:
Which of your blog articles received the most ...
Predicting links for network data
NETWORKS, PREDICT EDGES
Can we predict if two nodes in the graph are connected or not?
But let’s make it very practical:
Let’s say you work in a social media company and your boss asks you to create
a model to predict who will be friend...
Generalized fiducial inference on quantiles
My new package ‘gfiExtremes’ is on
CRAN
now. So it is time to present it.
This package allows to get confidence intervals about the quantiles of
any reasonable distribution (although... [Read more...]
Monte Carlo Simulation of Bernoulli Trials in R
Background
A user on Stackoverflow recently asked a question about a program to generate Monte Carlo simulations on Bernoulli trials to calculate coverage percentages using Wald confidence intervals. One of the problems in the code is that probability...
3 Top Business Intelligence Tools Compared: Tableau, PowerBI, and Sisense
Business Intelligence (BI) is used to transform data into actionable insights that provide value to an organization and help achieve its business goals. Reports and dashboards are go-to approaches for modern-day business intelligence tools. At Appsilon, we are big advocates of R and R Shiny, but we also have significant ...
lmDiallel: a new R package to fit diallel models. The Hayman’s model (type 1)
In a previous post we have presented our new ‘lmDiallel’ package (see this link here and see also the original paper in Theoretical and Applied Genetics). This package provides an extensions to fit a class of linear models of interest for plant breeders or geneticists, the so-called diallel models. In ... [Read more...]
lmDiallel: a new R package to fit diallel models. The Hayman’s model (type 1)
In a previous post we have presented our new ‘lmDiallel’ package (see this link here and see also the original paper in Theoretical and Applied Genetics). It provides several extensions to the lm() function in R, to fit a class of linear models of interest for plant breeders or geneticists, ... [Read more...]
Maximum Likelihood Distilled
We all hear about Maximum Likelihood Estimation (MLE) and we often see hints of it in our model output. As usual, doing things manually can give a better grasp on how to better understand how our models work. Here’s a very short example impl... [Read more...]
How to solve Sudoku with R
In this post we discuss how to write an R script to solve any Sudoku puzzle. There are some R packages to handle this, but in our case, we’ll write our own solution. For our purposes, we’ll assume the input Sudoku is a 9×9 grid. At the end result, ...
LondonR Talks – Computer Vision Classification – Turning a Kaggle example into a clinical decision making tool
I had the pleasure of speaking at the last LondonR event of 2020. What a strange year it has been? But this put the icing on the cake. The premise The premise of my talk was to take a novel Kaggle parasite cell dataset and advocate how this type of classification ... [Read more...]

collapse might rock your world
The NHS-R Community site prompted this post, specifically a question to the help-with-r channel on Slack.
Someone asked about obtaining unique values in a 60M row / 6 column dataset.
Naturally, data.table came up, and a few of us made sugg... [Read more...]

Rectangling (Social) Network Data
In this tutorial I will show you how we go from network data to a
rectangular format that is suited for machine learning.
Many things in the world are graphs (networks). For instance: real-life friendships, business interactions, links between websites and (digital) social networks. I find graphs (the formal name ...
Warspeed 5 — priors and models continued
My last 4 posts have all focused on the
vaccines being produced to fight COVID-19. They have primarily focused on
Bayesian methods (or at least comparing bayesian to frequentist methods). This
one follows that pattern and provides expanded cover...
