scipy.stats.anglit() is an anglit continuous random variable that is defined with a standard format and some shape parameters to complete its specification.
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 : anglit continuous random variable
Code #1 : Creating anglit continuous random variable
# import scipy from scipy.stats import anglit numargs = anglit.numargs [ ] = [0.6, ] * numargs rv = anglit() print ("RV : \n", rv) |
Output :
RV : <scipy.stats._distn_infrastructure.rv_frozen object at 0x0000029484AA02E8>
Code #2 : anglit random variates and probability distribution function.
import numpy as np quantile = np.arange (0.01, 1, 0.1) # Random Variates R = anglit.rvs(scale = 2, size = 10) print ("Random Variates : \n", R) # PDF R = anglit.pdf(quantile, loc = 0, scale = 1) print ("\nProbability Distribution : \n", R) |
Output :

Code #3 : Graphical Representation.
import numpy as np import matplotlib.pyplot as plt distribution = np.linspace(0, np.minimum(rv.dist.b, 5)) print("Distribution : \n", distribution) plot = plt.plot(distribution, rv.pdf(distribution)) |
