<p>The mean AMR distance is effectively <a href="https://en.wikipedia.org/wiki/Standard_score" class="external-link">the Z-score</a>; a normalised numeric value to compare AMR test results which can help to identify similar isolates, without comparing antibiograms by hand.</p>
<p>MIC values (see <code><a href="as.mic.html">as.mic()</a></code>) are transformed with <code><a href="https://rdrr.io/r/base/Log.html" class="external-link">log2()</a></code> first; their distance is thus calculated as <code>(log2(x) - mean(log2(x))) / sd(log2(x))</code>.</p>
<p>R/SI values (see <code><a href="as.rsi.html">as.rsi()</a></code>) are transformed using <code>"S"</code> = 1, <code>"I"</code> = 2, and <code>"R"</code> = 3. If <code>combine_SI</code> is <code>TRUE</code> (default), the <code>"I"</code> will be considered to be 1.</p>
<p>For data sets, the mean AMR distance will be calculated per column, after which the mean per row will be returned, see <em>Examples</em>.</p>
<p>Use <code>amr_distance_from_row()</code> to subtract distances from the distance of one row, see <em>Examples</em>.</p>

<h2 id="interpretation">Interpretation<a class="anchor" aria-label="anchor" href="#interpretation"></a></h2>
<p>Isolates with distances less than 0.01 difference from each other should be considered similar. Differences lower than 0.025 should be considered suspicious.</p>
