<p>To summarize the comments:</p>

<ol>
<li><p>Make [quantile-function] a synonym of [inverse-cdf]. You can ping @Xian and ask him to vote, but apart from that there are no eligible voters, so we would need a moderator to approve.</p></li>
<li><p>Check if some threads in [quantiles] need to be retagged into [quantile-function]. Going through <a href="https://stats.stackexchange.com/search?tab=votes&amp;q=%5bquantiles%5d%20%22quantile%20function%22%20is%3aquestion">this search with 22 results</a> should probably be enough. I see some questions like <a href="https://stats.stackexchange.com/questions/18438">Does a univariate random variable&#39;s mean always equal the integral of its quantile function?</a> - definitely a candidate for retagging. </p>

<p><strong>Update:</strong> I retagged a couple.</p></li>
