Their beliefs in treatment and prognosis may contribute to practices of variable quality and appropriateness.
In place of Viète's notation he initiated the modern practice of denoting variables by letters at the end of the alphabet (x, y, z) and parameters by letters at the beginning of the alphabet (a, b, c) and of using exponential notation to indicate powers of x (x2, x3,…).
To increase registered nurses' (RNs') practice of EBP, variables associated with such activities need to be explored.
Two separate hierarchical regression analyses were conducted to determine how much variance in the RDQ score and AUCG could be explained by the religious beliefs and practices of Buddhism variables after controlling for potential confounder variables.
Two hierarchical regression models were built to determine how much variance in disability and psychological stress could be explained by religious beliefs and practices of Buddhism variables after controlling for potential confounder variables.
Data dredging is the practice of drawing explicator variables blindly from a large number of possible hypotheses [60], [61]: "Running all possible models is a thoughtless approach and runs the high risk of finding effects that are, in fact, spurious if only a single model is chosen for inference" [62].
We suggest that the practice of categorizing continuous variables for easier use of prediction scores be discouraged, as it decreases performance and is unnecessary nowadays.
All variables were entered in the first step and the religious beliefs and practices of Buddhism variable was entered in the second step.
Perhaps the most obvious example within frequentist practice is the choice of variables to be included in a model.
In practice, because the number of variables associated with the BQ factors numbers in the thousands, the original set of predictor variables is replaced by a large, but manageable, number of principal components sufficient to account for at least 90% of the variance.
