A Gentle Introduction to Bayesian Analysis: Applications to Developmental Research
Bayesian statistical methods are becoming ever more popular in applied and fundamental research. In this study a gentle introduction to Bayesian analysis is provided. It is shown under what circumstances it is attractive to use Bayesian estimation, and how to interpret properly the results. First, the ingredients underlying Bayesian methods are introduced using a simplified example. Thereafter, the advantages and pitfalls of the specification of prior knowledge are discussed. To illustrate Bayesian methods explained in this study, in a second example a series of studies that examine the theoretical framework of dynamic interactionism are considered. In the Discussion the advantages and disadvantages of using Bayesian statistics are reviewed, and guidelines on how to report on Bayesian statistics are provided.

A sentence in the third paragraph of page 847 is incorrect: it should be “by decreasing its variance” (with many thanks to Mercy Manyema and Evie Izeboud for letting me know). Hereby the corrected version:
Figure 1e shows that we can increase the precision of our prior distribution by decreasing its prior variance.
