As a more precise variable, BF% measured by BIA indicated an association between fatness and CRF, while BMI failed to exclude the confounding effect of lean body mass.
The one unit increment in SOREMP can induce larger increase in the odd of being NT1; however, the mean REM sleep latency may be a more precise variable because of its narrower CI.
We used a sonomicrometric determination of ventricular dimension to examine the effect of ischemia and reperfusion on the work-length relationship in the intact heart to develop a useful and precise variable of ventricular contractile response to injury.
In both models, a social variable best explained variation in survival, but the precise variable differed between fetuses and infants.
Precise variable definitions and clear reporting of collection methods can assist in identifying these differences to improve interpretation of results.
The secret sauce lies in identifying the precise variables that best predict the outcome of cases that go to verdict, and from that, synthesizing those variables into an algorithm that can be used to predict the verdict in new cases.
At the end of the continuum, there may be more precise variables and predicted relationships.
To make analysis results more reliable, more precise variables of work experience (age) and human capital (education degree is permitted to change with time) are employed, together with controls over organization variables (including company type, unit size, and occupation categories) that may vary with time.
"We still don't know the precise variables behind the formation of particular shapes," Brunnin wrote on his blog, "although researchers are continually working on theoretical equations to predict snowflake shapes".
Both proxies accord with the empirical expectations of (Day et al. 2007) and are rendered essential by the available data, even if the proxies are imperfect: the precise variables that are theoretically interesting are often empirically inaccessible.
