Hi everyone

Instats is pleased to be offering free seminars on Using Confidence Intervals for Visual Testing for R (Oct 25) and Stata (Nov 1), with professor David Armstrong from the University of Western Ontario:

Confidence intervals and visualizations of them are common in the presentation of statistical results. Since their invention in the 1930's, researchers have recognized that readers will try to make inferences comparing estimates by evaluating whether confidence intervals overlap. A long line of research has discussed the pitfalls of this and attempted to build inferences around the probability that confidence intervals overlap under the null hypothesis - essentially burdening the visual display with an additional hypothesis testing function. To improve on this, these seminars will explore new visual tools that allow researchers to understand the precision of their estimates and to visually compare different groups or conditions in a meaningful and statistically defensible way. Designed for researchers across many disciplines, this workshop will equip participants with the expertise needed to leverage confidence intervals effectively using R and Stata.

Instats is also offering free seminars on Switching from SPSS to R <https://instats.org/seminar/switching-from-spss-to-r-free-2-hour-se2> (Nov 5) and Efficient Programming in R <https://instats.org/seminar/efficient-programming-using-r-free-semi2> (Jan 27). We look forward to seeing you there!
