# A comment on examples

+ From this point on we will try to make use of published studies as examples in lectures.

+ These studies will be selected because they...
--
  + **are in open source journals** so we can read it
--
  + **have openly available data** so we can analyse it
--
  + **have openly available code** so we can see exactly how the authors did it
--

+ The use of an example does not mean we...
--
  + **agree with the authors**; academia is a place for debate, we won't censor
--
  + **think they are perfect studies**; no study is perfect and careful critique is good practice
--
  + **think they are perfect write ups**; there are many styles with pros and cons
