Mixed-frequency Regression Modelling with Some Financial Applications
Virmantas Kvedaras (Vilnius University)
Regression modelling alternatives are considered whenever the regularly sampled explanatory variables are observed at a higher frequency than the dependent one. The ordered weighted aggregation (OWA) and the mixed data sampling (MIDAS) alternatives are discussed in more detail. An LM-type test is proposed to detect the non-linearity induced by the OWA-type effects. Its small sample properties are compared with the established tests for omitted non-linearity. Next, the statistical origin is defined of the non-linear restriction on parameters imposed in the MIDAS regressions, and the tests for its empirical adequacy are characterized in regressions with finite and infinite number of higher-frequency lags of explanatory variables. The relevance of OWA-type effects and the application of the MIDAS testing are illustrated using the stock exchange indices data.
