19 This means that the baseline hazard represents the age specific mortality rate for a reference individual, and the estimated hazard ratios are mortality rate ratios relative to the age specific mortality rate of the reference individual.
Prevalence ratios (PR) were calculated to compare supplement use rates for subgroups of interest against rates for a reference group (e.g., herbal use among women aged 75 79 vs. aged 65 74).
where K aA is the Doppler FM rate of the reference target A, and K s is the coefficient of azimuth-variant component of the Doppler FM rate.
The death rate was twice as high as the expected death rate in a reference group of Stockholm males and females of the same age distribution [ 11].
One reason for such difference is that the rate of a P-frame referenced from a P-frame is different than the rate of the P-frames referenced from an SP-frame due to the difference in the visual quality of the two reference frames.
Using 90% accuracy rate as a reference should of course not replace the need for drawing upon computer corpora for constructing an initial version of a WAF test, as discussed earlier.
The respiration rate at a reference temperature of 20 °C decreased from 25.1 mg CO2 kg DW−1 h−1 one week after harvest to 16.2 and 11.5 mg CO2 kg DW−1 h−1 three and six weeks after harvest, respectively.
We also calculated the attack rate in a reference ring of 5-10 km around each potential source farm and used this to compute relative risks (RR) for each 1 km concentric ring.
