| Description |
English: Random data points and their linear regression. Created with the following Sage (http://sagemath.org) commands:
X = RealDistribution('uniform', [-20, 60])
Y = RealDistribution('gaussian', 1.5)
f(x) = 3*x/20 + 5
xvals = [X.get_random_element() for _ in range(100)]
data = [(x, f(x) + Y.get_random_element()) for x in xvals]
m, b = var('m b')
g(x) = m*x + b
g(x) = g(x).subs(find_fit(data, g, solution_dict=True))
p = list_plot(data) + plot(g, (x, -20, 60), color='red')
p.save('linear_regression.svg')
