Jun 29, 2016 · I get a linear graph when trying to plot exponential function: import math import numpy as np import matplotlib.pyplot as plt def graph(formula, x_range): x = np.array(x_range) y = eval(formula) plt.plot(x, y) graph('100*(np.power(0.8, x))', (0,100))

An exponential continuous random variable. As an instance of the rv_continuous class, expon object inherits from it a collection of generic methods (see below for the full list), and completes them with details specific for this particular distribution.

May 6, 2022 · This tutorial explains how to use the exponential distribution in Python. How to Generate an Exponential Distribution. You can use the expon.rvs(scale, size) function from the SciPy library in Python to generate random values from an exponential distribution with a specific rate parameter and sample size:

Mar 20, 2019 · scipy.stats.expon() is an exponential 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

Firstly I would recommend modifying your equation to a*np.exp(-c*(x-b))+d, otherwise the exponential will always be centered on x=0 which may not always be the case. You also need to specify reasonable initial conditions (the 4th argument to curve_fit specifies initial conditions for …
