它由三个参数来描述,分别是尺度参数(scale parameter),形状参数(shape parameter)和位置参数(position parameter)。 1. 尺度参数(Scale Parameter):尺度参数表示分布的尺度或者说是分布的缩放因子。它决定了分布的范围和形状。通常用符号β表示。尺度参数越大,分布的范围越宽,尾部越长。 2. 形状参数(Shape Parameter...

It is found that the numerical values of the shape and scale parameters vary over a wide range for these weather stations. The wind data, obtained from the city area, showed that the two parameters of Weibull distribution both have a tendency to grow within the analyzed years. Because the ...
Most of time the shape parameter () is close to 1.0. Both the shape and scale (路) parameters significantly reflect product durability. Finally, the reliability trend is affected by parameters set on varying production lots and will decline to 0.95 and 0.90 while operational time moves to 1.5...
The reliability function of a 2-parameter Weibull distribution is given byR(t)=exp(−(t/η)β)while the unreliability function of a 2-parameter inverse Weibull distribution is given byF(t)=exp(−(η/t)β)The parameters β and η are called shape and scale parameter, respectively. For ...
