[R-SIG-Finance] Confidence Intervals for Visual Testing - free seminars

[Michael Zyphur]

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!


Best wishes
