Having read many books&#x2F;online courses, I strongly recommend this:
<a href="http:&#x2F;&#x2F;www.amazon.com&#x2F;Doing-Bayesian-Data-Analysis-Second&#x2F;dp&#x2F;0124058884&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;Doing-Bayesian-Data-Analysis-Second&#x2F;dp...</a><p>It gives a gentle but through introduction from first principles; lots of good intuition and &#x27;why&#x27;.<p>It works well with
&quot;Probabilistic Programming &amp; Bayesian Methods for Hackers&quot;
also mentioned, but I&#x27;d start with this. It is much more accessible than many other introductory books, IMO.
