摘要
The present paper applies a least square method to estimate parameters of a Weibull distribution, with the shape parameter lying in the range 0-3, where other methods like the maximum likelihood method are generally not applicable. Further, Fisher's F-test is employed to find the goodness of fit of a straight line. Two approximate methods have also been developed for the remaining range of the shape parameter. Illustrations are provided wherever necessary.
