Python | Scipy stats.halfgennorm.isf() method

With the help of stats.halfgennorm.isf() method, we can get the value of inverse survival function which is inverse(1 – cdf) by using stats.halfgennorm.isf() method.

Syntax : stats.halfgennorm.isf(x, beta)
Return : Return the value of inverse survival function.

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

# import halfgennorm
from scipy.stats import halfgennorm
beta = 1

# Using stats.halfgennorm.isf() method
gfg = halfgennorm.isf(0.3, beta)

print(gfg)

Output :

1.2039728043259357

Example #2 :

# import halfgennorm
from scipy.stats import halfgennorm
beta = 4

# Using stats.halfgennorm.isf() method
gfg = halfgennorm.isf(0.9, beta)

print(gfg)

Output :

0.09064147135377666
