In this context, we will develop in the second section a new approach to better exploit the option prices information content through the elimination of bias caused by the daily variation of maturities.
As we know, continuous brightness temperature data includes basic earth temperature field (direct circulating part), annual variation temperature field, daily variation temperature field, temperature changes caused by the rain clouds, cold-heat air currents, and other factors (including earthquakes).
Literature was searched in (a) the Medline database, using the key words chronobiology OR biological variation OR biological variability OR physiological variation OR physiological variability OR intraindividual variation OR intraindividual variability OR daily variation OR daily variability OR circadian rhythm OR diurnal rhythm AND prostate-specific antigen; (b) local literature databases at the involved institutions; and (c) recent reviews (4-6).
The use of a diary method in this study has enabled Butler and colleagues to show that there is substantial daily variation in the amount of work-family conflict and facilitation experienced by non-professional workers with dependent children.
To adjust for the daily variation in the number of radio-collared moose within hunting areas, we used the logarithm of all radio-collared moose within hunting areas as an offset variable; i.e., the exponent of the parameter (M) equal to 1 (see equation 1).
