| ABSTRACT |
|
Twodimensional warranty data can be modelled using two different approaches： twodimensional point process and onedimensional point process with usage as a function of age. The first approach has three different models. First of all, bivariate model is appealing but is not appropriate for explaining warranty claims. Next, the rest of the two models (marked point process, and counting and matching on both directions independently) are more appropriate for explaining warranty claims. However, the second one (counting and matching on both directions independently) assumes that the two variables (variables representing the twodimensions) are independent. Last of all, onedimensional point process with usage as a function of age is also promising to explain the twodimensional warranty claims. But the models or variations of them need more investigation to be applicable to real warranty claim data. |
