WebIn other words, the Weibull routine reveals, rather than masks, the correct shape of the data's density curve. For example, a Weibull shape factor of 1.0 represents an exponential distribution. A shape factor of 2.0 is a Raleigh distribution, while a Weibull shape factor of about 3.0 or above represents an approximately normal distribution. WebA Weibull modulus of m = 4 was chosen from theoretical analysis, and it was also used to minimize the sample size effects. In the survey of the literature for the present study, …
