The knots of the spline functions are estimated as free parameters within a joined estimation process together with the parameters of the mean, the conditional variance and the spline function. With the help of this method, the knots are placed in regions where the unconditional variance is not smooth. The results are tested within an extensive simulation study and an empirical study employing the S\u0026amp;P500 index.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer Gabler\u003c\/p\u003e \u003cp\u003ePublication Date: 2022-07-28\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783658386177\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-3-658-38618-4\u003c\/p\u003e \u003cp\u003eDimensions: 210cm x148cm\u003c\/p\u003e \u003cp\u003ePages: 237\u003c\/p\u003e ","brand":"Springer Fachmedien Wiesbaden","offers":[{"title":"Default Title","offer_id":46548028129420,"sku":"9783658386177","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783658386177.jpg?v=1776051257","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783658386177","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
