WebWeibull Distribution Basic Concepts Definition 1: The Weibull distribution has the probability density function (pdf) for x ≥ 0. Here β > 0 is the shape parameter and α > 0 is the scale parameter. The cumulative distribution function (cdf) is Let p = 1 – exp (- (x/α)β). Then 1 – p = exp (- (x/α)β). Webweibull_mle(phi, k_0 = 1) moge_mle(phi, lambda_0 = 1, alpha_0 = 1, theta_0 = 1) Arguments phi a vector with residual values used to estimate the parameters. dist assumed distribution for the noise in the data.
