In order to estimate the contribution of AI to HIV and STI incidence among FSW and transmission to their sexual partners, it is first necessary to accurately described AI practice in this group. To estimate this contribution, we need data on the proportion of FSW who practise AI and at what...
The recording of a disease mortality rate serves as statistical data that is used to monitor the causes of death and life expectancy, and allows for the determination of developmental policies in an area. Mortality rate data is also closely related to incidence rate data. As for analyzing the ...
Approximately 10% of parents (n = 36) did not provide complete weight and height data needed to calculate BMI. Parents with missing BMI data were more likely to have lower household incomes, level of education, and children who were overweight or obese, though these differences were not ...
The standard deviation of the unknown prevalence is required to calculate the size of a sample. As the proportion (p) was unknown, a conservative estimate was set at p = 0.50 to produce the most conservative estimate of the sampling error. With a confidence level of 95% and a margin of ...
waveforms observed in the Greenland Sea and Fram Strait (seeSection 2.1) are employed in the classification process. In order to calculate the altimeter backscatter values, different features stored in the SGDR dataset, for example, atmospheric attenuation and instrumental corrections (e.g., sigma ...
