Good question! If p-value of LOF is low, the model is not fitting well. You can try transformations such as box cox. If you still get a similar p-value, you will need to decide whether some more factors need to be added, or change levels or use the model with caution.

In this example, we are sure about all the raw data are operation time of failure, right? Another question: Isn't a smaller Anderson-Darling value indicative of a better goodness-of-fit? Why is the Weibull distribution considered the most appropriate when the exponential distribution has the smallest value?
@instituteofqualityandrelia7902
@instituteofqualityandrelia7902 Ай бұрын
Hello friend, that is a very good question! Yes, the lower value of AD shows better fit. Choosing Weibull is still safe as Exponential is only a special case of Weibull with a shape parameter of 1.

Thanks for the explanation, but still i have question. In a real case e.g determining the components reliability of a machine, what is the ß value? Because sometimes, when it broke, u just need to repair the components and it will run again (basically we use MTBF on this situation), and sometimes when it broke you need to change the components so it would start again (non repairable units, and this we use MTTF). What is the ß value then?
