Testing for multivariate volatility functions using minimum volume sets and inverse regression
Polonik, Wolfgang; Yao, Qiwei - London School of Economics (LSE) - 2008
We propose two new types of nonparametric tests for investigating multivariate regression functions. The tests are based on cumulative sums coupled with either minimum volume sets or inverse regression ideas; involving no multivariate nonparametric regression estimation. The methods proposed...
