Dennis Hendriks updated MATH-733:
---------------------------------

    Attachment: lognormal_distribution.patch

Implementation of the log-normal distribution. Implementation based on 
Wikipedia formulas and the already present implementation of the normal 
distribution.

Unit tests included. Also based on test cases for the normal distribution.

Checkstyle fails:

{code}
<file 
name="src/main/java/org/apache/commons/math/distribution/LogNormalDistribution.java">
<error line="0" severity="error" message="Got an exception - 
java.lang.RuntimeException: Unable to get class information for @throws tag 
&apos;NotStrictlyPositiveException&apos;." 
source="com.puppycrawl.tools.checkstyle.TreeWalker"/>
</file>
{code}

However, it does so for most of the distributions...
