Weibullmallinnusta
Weibullmallinnusta, also known as Weibull regression, is a statistical method used to analyze the relationship between a dependent variable and one or more independent variables. It is particularly useful in reliability engineering, survival analysis, and other fields where the time to failure or event occurrence is of interest. The Weibull distribution, which is a continuous probability distribution, is at the core of this method. It is characterized by its shape parameter, which determines the distribution's form, and its scale parameter, which affects the spread of the data.
In Weibull regression, the dependent variable is typically the logarithm of the time to failure or event
Weibull regression can be estimated using maximum likelihood estimation, which involves finding the parameter values that
Weibull regression has several advantages over other regression methods. It can handle censored data, which occurs
