 ### Computed Properties
 
+#### InvGamma.prototype.entropy
+
+Returns the [differential entropy][entropy].
+
+```javascript
+var invgamma = new InvGamma( 4.0, 12.0 );
+
+var entropy = invgamma.entropy;
+// returns ~1.996
+```
+
 #### InvGamma.prototype.kurtosis
 
 Returns the [excess kurtosis][kurtosis].
