Abstract:
    The completeness of sample is especially important for the research of
    quasar and using data in one wavelength, such as in radio, infrared,
    optical or X-ray selection, to make candidate selection always suffers
    significant selection effect to some extent. Fortunately, some large
    area surveys have become increasingly prevalent across all wavelengths
    over the past decade, such as SDSS, NVSS, FIRST, RASS, etc. These
    surveys make it possible to select candidates in multiple wavelengths
    and the resulting sample is more complete.
