The paired sample t-test, sometimes called the dependent sample t-test, is a statistical procedure used to determine whether the mean difference between two sets of observations is zero. In a paired sample t-test, each subject or entity is measured twice, resulting… The post Paired sample t-test using R appeared first ...

The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of three or more independent (unrelated) groups. This guide will provide a brief introduction to the one-way ANOVA, including the… The post One-Way ANOVA using R appeared first on Statistical ...

A two-way ANOVA test is a statistical test used to determine the effect of two nominal predictor variables on a continuous outcome variable. A two-way ANOVA tests the effect of two independent variables on a dependent variable. This blog post contains… The post Two-Way ANOVA using R appeared first on ...

Cluster analysis is a statistical technique that groups similar observations into clusters based on their characteristics. It is a statistical method of processing data. A good cluster analysis produces high-quality clusters with high inter-class correlation. This blogpost contains the following… The post Cluster analysis using R appeared first on Statistical ...

Fixed width files? What are those?

Fixed width files? What are those? Well, imagine your entire dataframe/ tibble/ data.table is in a single column. That’s it, over 200 columns, in one. Each row is a very long string. Sounds fun right? Ideally, there would be delimiters ...

How can you be sure that the contents of an email haven’t been tampered with? The best approach would probably be to have a digital signature on each component of the message. Perhaps I’ll look at integrating that into {emayili} some time in the future. However, today I’...

A puzzle from The Riddler this week returning to the ranking of climbing competitors in Tokyo. And asking for the maximin score, that is, the worst possible absolute score guaranteeing victory. In the case of eight competitors, a random search for a maximin over 10⁶ draws leads to a value of 48=1...
