This post explores the performance of various data formats in R for reading and writing operations, highlighting file size, speed, and memory usage.
The ability to accurately model and interpret complex data sets is paramount. This technical exploration delves into three sophisticated modelling techniques: Polynomial Models, Fractional Polynomials, and Spline Models. Each of these models serves as a fundamental tool in the statistical toolkit, enabling us to capture and understand the intricacies of linear and non-linear relationships inherent in real-world data.
General idea The Concordance Correlation Coefficient (CCC) is a statistical measure designed to evaluate the agreement between two sets of measurements, such as those represented by two random variables, $X$ and $Y$.
Introduction In R programming, efficiency is key. Snippets, small reusable blocks of code, are a cornerstone in achieving this. This post delves into the world of snippets, offering both novice and seasoned R programmers insights into their power and versatility.
The golem package In the world of R programming, Shiny applications let us make interactive web apps using R code. The golem package (Fay et al. 2021) makes it easier to develop these apps.
tl;dr Many different variables affect how the pandemic progresses and it is extremely difficult to identify each one, and precisely measure them. The data we have is surely innacurate, but could be a good proxy for understanding the behaviour of the coronavirus outbreak We developed a statistical model to obtain short-term forecasts of the number of COVID-19 cases We constantly update forecasts and make all results freely available to any country in the world through a web app How many people will get infected tomorrow?

Overview of the Seven Steps The seven steps proposed by Hilton et al. (2019) present an intriguing strategy for initiating a new project involving programming. This approach is concisely summarized in Figure 1.
Introduction Expressions in C++ are fundamental constructs made up of operators, constants, and variables, following the language’s syntactical rules. Every expression is a segment of a code that returns a value.
Introduction When programming in C, a fundamental step is understanding variable assignment. C offers various data types, and here we focus on int, used for integer data. There are two primary methods to define an int variable:
