<p>This means that at least one of those three tags (<a href="https://stats.stackexchange.com/questions/tagged/time-series" class="post-tag" title="show questions tagged &#39;time-series&#39;" rel="tag">time-series</a>, <a href="https://stats.stackexchange.com/questions/tagged/arima" class="post-tag" title="show questions tagged &#39;arima&#39;" rel="tag">arima</a> or <a href="https://stats.stackexchange.com/questions/tagged/var" class="post-tag" title="show questions tagged &#39;var&#39;" rel="tag">var</a>) were favorited by you. This feature facilitates users finding questions of their interest.</p>

<p>On the other hand, ignored tags makes questions labeled with them to appear with less visibility (shadowed?).</p>

<p>See the screenshot below. Just as an example, I added <a href="https://stats.stackexchange.com/questions/tagged/repeated-measure" class="post-tag" title="show questions tagged &#39;repeated-measure&#39;" rel="tag">repeated-measure</a> as a favorite tag and <a href="https://stats.stackexchange.com/questions/tagged/machine-learning" class="post-tag" title="show questions tagged &#39;machine-learning&#39;" rel="tag">machine-learning</a> as an ignored tag.</p>
