Yet another look at MIDAS regression
نویسنده
چکیده
A MIDAS regression involves a dependent variable observed at a low frequency and independent variables observed at a higher frequency. This paper relates a true high frequency data generating process, where also the dependent variable is observed (hypothetically) at the high frequency, with a MIDAS regression. It is shown that a correctly specified MIDAS regression usually includes lagged dependent variables, a substantial number of explanatory variables (observable at the low frequency) and a moving average term. Next, the parameters of the explanatory variables unlikely obey certain convenient patterns, and hence imposing such restrictions in practice is not recommended. JEL Code: C32

Translation, cross-cultural adaptation and reliability of the German version of the migraine disability assessment (MIDAS) questionnaire
BACKGROUND The Migraine Disability Assessment (MIDAS) is a brief questionnaire and measures headache-related disability. This study aimed to translate and cross-culturally adapt the original English version of the MIDAS to German and to test its reliability. METHODS The standardized translation process followed international guidelines. The pre-final version was tested for clarity and compreh...

Integrin-ligand interactions are regulated in a complex manner by divalent cations, and previous studies have identified ligand-competent, stimulatory, and inhibitory cation-binding sites. In collagen-binding integrins, such as 2 1, ligand recognition takes place exclusively at the subunit I domain. However, activation of the I domain depends on its interactionwith a structurally similar domain...
متن کاملSome Experiences with Secure Management
This paper describes work carried out in the ESPRIT MIDAS project to provide secure management facilities. The work is based on extensions to the OSI CMIP management protocol which provide for mutual authentication at association set-up and integrity checks in all PDUs. The first version of this mechanism has been implemented and tested; in practice it has been found to be rather slow in operat...
متن کاملMIDAS-W: A Workstation-based Incoherent Scatter Radar Data Acquisition System
The Millstone Hill Incoherent Scatter Data Acquisition System (MIDAS) is based on an abstract model of an incoherent scatter radar. This model is implemented in a hierarchical software system, which serves to isolate hardware and low-level software implementation details from higher levels of the system. Inherent in this is the idea that implementation details can easily be changed in response ...
