The Asteroid Impact & Deflection Assessment (AIDA) mission is planning to visit the Didymos binary system in 2022 in order to perform the first demonstration ever of the kinetic impact technique.
We defined donation status in each visit as a binary variable in our data set (donation =1, no donation =0).
The average number of joints smoked per week in the 6 months preceding the study visit and a binary indicator of marijuana smoking were updated at each study visit.
The predictors of the future hemoglobin level are age, season, hemoglobin levels at the previous visits, and a binary variable indicating whether a donation was made at the previous visit.
Generalized mixed effects models (using Stata gllamm procedure; [ 9]) were used to assess change for any ER visits and hospitalizations (binary) from baseline to 6- and 12-month assessments controlling for age, sex, race/ethnicity, education, and number of chronic conditions.
Hospital use was analysed using a two-stage procedure to test for differences in binary (any visits or none) and continuous (number of visits in those having at least one visit) components.
Therefore, for each participant at each visit, there are fourteen binary indicators indicating the presence or absence of the fourteen HR-HPV genotypes, respectively.
CD4 count was coded as a numeric value at initial clinic visit and as a binary variable, defined as early presentation (CD4 > 350 cells/μl) or late presentation (CD4 ≤ 350 cells/μl) according to the 2011 Guidelines for antiretroviral therapy in Kenya [ 14].
Evolution of the true latent ability was assessed using a latent-class-specific linear mixed model with a class-specific quadratic age trend to account for non-linear cognitive decline; a binary 'first visit' variable was included as a common estimate across the classes to account for a potential learning effect between waves one and two but not between waves thereafter [ 17].
However, in order to examine the impact of exercising and visiting socialization venues, the binary treatments are defined by considering only whether there was some exercising activity or a visit to a socialization place or not.
