<p><strong><a target="_blank" href="https://xianblog.files.wordpress.com/2012/01/pict0448-e1326730756979.jpg"><img height="253" alt="gaarden tree, Jan. 16, 2012" width="350" class="wp-image-14294" src="https://xianblog.files.wordpress.com/2012/01/pict0448-e1326730756979.jpg?w=350&h=253"></a>A</strong> new version of the <a target="_blank" href="https://cran.r-project.org/web/packages/abcrf/index.html">R package abcrf</a> has been posted on Friday by Jean-Michel Marin, in conjunction with the <a target="_blank" href="http://arxiv.org/pdf/1605.05537v1.pdf">recent arXival</a> of our paper on point estimation via ABC and random forests. The new R functions come to supplement the existing ones towards implementing ABC point estimation:</p>
<ol>
<li><em>covRegAbcrf</em>, which predicts the posterior covariance between those two response variables, given a new dataset of summaries.</li>
<li><em>plot.regAbcrf</em>, which provides a variable importance plot;</li>
<li><em>predict.regabcrf</em>, which predicts the posterior expectation, median, variance, quantiles for a given parameter and a new dataset;</li>
<li><em>regAbcrf</em>, which produces a regression random forest from a reference table aimed out predicting posterior expectation, variance and quantiles for a parameter;</li>
<li><em>snp</em>, a simulated example in population genetics used as reference table in <a target="_blank" href="https://xianblog.wordpress.com/2015/10/21/abc-model-choice-via-random-forests-accepted/">our Bioinformatics paper</a>.</li>
</ol>
<p>Unfortunately, we could not produce directly a <em>diyabc2abcrf</em> function for translating a regular <a target="_blank" href="http://www1.montpellier.inra.fr/CBGP/diyabc/">DIYABC</a> output into a proper abcrf format, since the translation has to occur in <a target="_blank" href="http://www1.montpellier.inra.fr/CBGP/diyabc/">DIYABC</a> instead. And even this is not a straightforward move (to be corrected in the next version of <a target="_blank" href="http://www1.montpellier.inra.fr/CBGP/diyabc/">DIYABC</a>).</p>
