With the help of sympy.stats.PowerFunction()
method, we can get the continuous random variable which represents the Power Function distribution.
Syntax :
sympy.stats.PowerFunction(name, alpha, a, b)
Where, a, b and alpha are real number.Return : Return the continuous random variable.
Example #1 :
In this example we can see that by using sympy.stats.PowerFunction()
method, we are able to get the continuous random variable representing power function distribution by using this method.
# Import sympy and PowerFunction from sympy.stats import PowerFunction, density
from sympy import Symbol, pprint
z = Symbol( "z" )
alpha = Symbol( "alpha" , positive = True )
a = Symbol( "a" , positive = True )
b = Symbol( "b" , positive = True )
# Using sympy.stats.PowerFunction() method X = PowerFunction( "x" , alpha, a, b)
gfg = density(X)(z)
print (gfg)
|
Output :
(-2*a + 2*z)/(-a + b)**2
Example #2 :
# Import sympy and PowerFunction from sympy.stats import PowerFunction, density, variance
from sympy import Symbol, pprint
z = Symbol( "z" )
alpha = 2
a = 0
b = 1
# Using sympy.stats.PowerFunction() method X = PowerFunction( "x" , alpha, a, b)
gfg = density(X)(z)
pprint(variance(gfg)) |
Output :
1/18
