Return : Return the log of probability density function.

Example #1 :
In this example we can see that by using `stats.halfgennorm.logpdf()` method, we are able to get the log of probability density function by using this method.

 `# import halfgennorm``from` `scipy.stats ``import` `halfgennorm``beta ``=` `2`` ` `# Using stats.halfgennorm.logpdf() method``gfg ``=` `halfgennorm.logpdf(``0.1``, beta)`` ` `print``(gfg)`

Output :

0.1107822376352453

Example #2 :

 `# import halfgennorm``from` `scipy.stats ``import` `halfgennorm``beta ``=` `4`` ` `# Using stats.halfgennorm.logpdf() method``gfg ``=` `halfgennorm.logpdf(``0.9``, beta)`` ` `print``(gfg)`

Output :

-0.5578281635781869
