Webb17 juni 2016 · 2 Answers. Exponential regression is the process of finding the equation of the exponential function ( y = a b x form where a ≠ 0) that fits best for a set of data. In linear regression, we try to find y = b + m x that fits … WebbExponential Distribution Plot. Given a rate of λ (lambda), the probability density function for the exponential distribution is: f ( x; λ) = λ e − λ x. for x ≥ 0. In the R documentation, the code for the exponential distribution’s density function is: dexp (x, rate = 1, log = FALSE) This first plot deals with the case when the rate ...
