Mixedeffects modeling — four hour workshop — part IV: LMEs
For an example analysis, we collated a .csv file of data from a repeated measures lexical decision experiment, which can be downloaded here. The code I have used in running the analysis described in this post can be found here. … Continue reading
Modelling – mixed effects – concepts

Mixed effects – continuing the extended example
As noted in a previous post, our mixed effects analysis of the ML lexical decision data suggested that RTs were influenced by significant effects due to: cAge + cART + cTOWRENW + cLength + cOLD + cBG_Mean + cLgSUBTLCD + … Continue reading
Modelling – extended example mixedeffects analysis
In the previous post, we ran through an example of a mixedeffects analysis completed using the lmer() function from the lme4 package (Bates, 2005; Bates, Maelchler & Bolker, 2013). We will not, yet, really fulfill the promise to develop our … Continue reading
