<p>Contains the analysis scripts for the meta-analysis on model fit ($R^2$) and additional analysis.</p> <p>The data of the current article is contained in the files produced by the scripts in the <code>data</code> component (<code>exp1_experimental.rda</code>, <code>exp2_experimental.rda</code>, <code>exp3a_experimental.rda</code>, and <code>exp3b_experimental.rda</code>), the data of Klauer et al. (2010) is also present in pre-prepared binary data files (<code>kbh_exp1_data.rda</code>, <code>kbh_exp3_data.rda</code>, and <code>kbh_exp4_data.rda</code>). </p> <p>The model fitting is performed by a separate file for each experiment which uses other files (and need the data):</p> <ul> <li>The main fitting files: <code>fit.exp1.models.R</code>, <code>fit.exp3.models.R</code>, <code>fit.exp3.models.R</code>, <code>fit.klauer.e1.models.R</code>, <code>fit.klauer.exp3.models.R</code>, and <code>fit.klauer.eexp4.models.R</code>.</li> <li>The model files: <code>orig.dualsource.R</code> (DSM), <code>orig.oaksford.R</code> (PROB), <code>new.oaksford.R</code> (EX-PROB), and <code>orig.kl.R</code> (KL).</li> <li>Further there are the reduced model files <code>pure_form.R</code> and <code>pure_knowledge.R</code> (mentioned in the general discussion).</li> <li>Helper files for fitting: <code>fit.function.R</code> and <code>weighting.functions.R</code></li> </ul> <p>The fitted values are saved in a separate file per experiment: <code>fits_e1.rda</code>, <code>fits_e2.rda</code>, <code>fits_e3.rda</code>, <code>fits_klauer_e1.rda</code>, <code>fits_klauer_e3.rda</code>, and <code>fits_klauer_e4.rda</code>.</p> <p>The meta-analysis and the additional analysis are performed by script <code>meta-analysis.R</code> which reads in the fitted values and produces the results reported in the manuscript as well as the results figures (<code>meta-analysis.pdf</code> and <code>meta_additional.pdf</code>). For the latter it needs the helper file <code>vioplot.R</code>.</p> <p>The analysis of the specific predictions of the DSM noted in the introduction are performed in file <code>novel_prediction.R</code> which produces the file <code>models_novel_prediction.rda</code>.</p>
