Example #1 :
In this example we can see that by using `stats.halfgennorm.ppf()` method, we are able to get the value of percentage point function by using this method.

 `# import halfgennorm``from` `scipy.stats ``import` `halfgennorm``beta ``=` `1`` ` `# Using stats.halfgennorm.ppf() method``gfg ``=` `halfgennorm.ppf(``0.3``, beta)`` ` `print``(gfg)`

Output :

0.3566749439387324

Example #2 :

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

Output :

0.9307267047740223
