"While we know that repetitive brain trauma is a necessary variable, it is not a sufficient variable," says Stern.
In other words, a region should contain a representation for the task control variable as a necessary (if not sufficient) condition for a region to play a functional role in control of this variable.
These results, on the one hand exclude problems of collinearity by the simultaneous use of these factors as independent variables in the same model, and validate the inclusion of body mass in the models as a variable necessary to control the effects of clutch size and duration of nestling period.
Because comparison of series-specific odds ratios and corresponding 95% confidence showed that odds ratios were largely in the same direction and their corresponding 95% confidence intervals overlapped between series, we also conducted combined series case-control comparisons with a study series indicator variable as a necessary covariate in logistic regression models.
Accept risk as a necessary evil.
How many papers do you know in which a group determines all available necessary variables, such as sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy?
Second, we did not include specific measures of severity in our analysis, such as the Pneumonia Severity Index or CURB-65, as we were missing several necessary variables.
If necessary, variables were transformed to approximate a normal distribution.
If necessary, variables were log10-transformed.
Given the substantial presence of imported pistachios from Turkey and from California, including COO as an explanatory variable is necessary.
Storage energy, commonly used in dynamic energy budget modelling as a predictor variable for reproductive output28,31 and necessary for den survival, gestation and lactation25, was a priori considered a likely determinant for litter size.
