I'm trying to calculate the shape and scale based on mean and standard deviation of a weibull distribution. If mean = 0 and sd = 1, the shape and scale both return NA. But for other values (such as mean = 1 and sd = 2), the result is perfect. Any requirement for the input parameters?

WebThe Weibull distribution is named after its originator, the Swedish physicist Waloddi Weibull, who in 1939 used it to model the distribution of the breaking strength of materials [ 3.4] and in 1951 for a wide range of other applications [ 3.5 ]. The distribution has been widely studied since its inception. Webexponential distribution (constant hazard function). When is greater than 1, the hazard function is concave and increasing. When it is less than one, the hazard function is convex and decreasing. t h(t) Gamma > 1 = 1 < 1 Weibull Distribution: The Weibull distribution can also be viewed as a generalization of the expo-
