<p>To be exact, <code>ebnm</code> uses a mixture of normal distributions rather than
  a mixture of point masses when
  $$\frac{\max(x) - \min(x)}{\min(s)} &gt; 3 \ \mathrm{max}_K;$$ for a

  only uses a mixture of normal distributions when <code>scale = "estimate"</code>;
  if parameter <code>scale</code> is set manually, then a mix
