scipy.stats.semicircular() is a semicircular continuous random variable. It is inherited from the of generic methods as an instance of the rv_continuous class. It completes the methods with details specific for this particular distribution.
Parameters :
q : lower and upper tail probability
x : quantiles
loc : [optional]location parameter. Default = 0
scale : [optional]scale parameter. Default = 1
size : [tuple of ints, optional] shape or random variates.
moments : [optional] composed of letters [‘mvsk’]; ‘m’ = mean, ‘v’ = variance, ‘s’ = Fisher’s skew and ‘k’ = Fisher’s kurtosis. (default = ‘mv’).Results : Semi-circular continuous random variable
Code #1 : Creating Semi-circular continuous random variable
# importing library from scipy.stats import semicircular numargs = semicircular .numargs a, b = 4.32, 3.18rv = semicircular (a, b) print ("RV : \n", rv) |
Output :
RV : scipy.stats._distn_infrastructure.rv_frozen object at 0x000002A9D843A9C8
Code #2 : Semi-circular continuous variates and probability distribution
import numpy as np quantile = np.arange (0.01, 1, 0.1) # Random Variates R = semicircular.rvs(a, b) print ("Random Variates : \n", R) # PDF R = semicircular.pdf(a, b, quantile) print ("\nProbability Distribution : \n", R) |
Output :
Random Variates : 4.041796830801463 Probability Distribution : [0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]
Code #3 : Graphical Representation.
import numpy as np import matplotlib.pyplot as plt distribution = np.linspace(0, np.minimum(rv.dist.b, 3)) print("Distribution : \n", distribution) plot = plt.plot(distribution, rv.pdf(distribution)) |
Output :
