A controlled variable is one which the researcher holds constant (controls) during an experiment. It is also known as aconstant variableor simply as a "control." The control variable is not part of an experiment itself—it is neither theindependentnordependent variable—but it is important becau...
Costs per patient will be the outcome variable and one dummy variable indicating the two models (with the Facility Model as the reference) will be the exposure variable. Other covariates include time and interaction terms between intervention dummies and time. To provide mean and 95% confidence ...
29, 30 Although child weight-for-age has been hypothesised to be a useful objective indicator of child diarrhoea,31 the strength of correlation with diarrhoea episodes can be highly variable. Our study has several limitations. We had to stop data collection earlier than desired in one of the ...
Another problem is defining intractability, or how many drugs should be tried before declaring a patient medically intractable, which remains an individual and variable decision. Nevertheless, it is now known that the chances of seizure control decline rapidly after the first few AED trials. Whether...
aThe properly terminated type-I square lattice. The highlighted (blue) sites indicate the waveguides that regulate the hoping termt3. They are associated with a variable index difference Δn3.bThe bulk band structure corresponding to an infinite lattice (both along thex- andy-direction), with ...
focused on patients who had died as a result of a DBI, also made evident differences in the frequency of WLST across European countries [27]. These differences probably reflected variable professional practices that in turn are influenced by cultural, religious and social factors in each country....
\(logit\left(p\right)={\text{log}}\left(\frac{p}{1-p}\right)= {\beta }_{0}+{\beta }_{1}X+{\tau }_{c}\), whereXis a binary variable (0 for usual care and 1 for SBIRT intervention),\({\tau }_{c}\)is a random effect for clustering within churches, andp = ...
Due to this difference, we grouped participants of FinG 1 and FinG 2 in different classes. We adopted the classification presented byHöst et al. (2005). They addressed experience as context variable in empirical studies and proposed a classification, which we show in Table14. The scale in ...
variables and 2) standardized coefficients (Betas), standard errors (SE), and p-values for the continuous variable. In addition, the effect sizes were calculated using Cohen’s d (i.e., M1– M2/ √(SD12 + SD22) / 2) [43] for weekly alcohol consumption and numbers needed to ...
in probability theory and mathematical statistics, one of the characteristics of a distribution of a random variable. For a random variable having probability density p(x), any point at which p(x) has a maximum is said to be a mode. Distributions with a single mode (called unimodal distribut...
