The phrase "a few predictors" is correct and usable in written English.
It can be used when referring to a small number of variables or factors that are used to make predictions in a statistical or analytical context.
Example: "In our study, we identified a few predictors that significantly influenced the outcome of the experiment."
Alternatives: "several predictors" or "some predictors".
So is the analysis still largely exploratory, or is there a clear focus on one or a few predictors?
Thus, it may be hard to assess the interplay between those factors based on a single or a few predictors.
It is observed that a few predictors outperformed the whole set of variables in predicting MACE within 72 h.
Although built on a subjective choice of a few predictors, the score seemed to have suitable predictive power and calibration.
This study expands our understanding that only a few predictors are needed in risk stratification of MACE within 72 h.
When time-invariant unobserved differences across communities are controlled for, only a few predictors remain significant and some estimated coefficients change substantially.
In general, existing empirical models based on longitudinal data include only a few predictor variables (e.g. cross-lag models with two independent variables; [ 71]).
The predictors that were described in this work were significantly better than the other predictors; however, there were a few dozen predictors that gave similar results.
In a prospective study, there were few predictors of which PWD would leave the home unattended and require an escort to return [ 2].
The Lasso serves as a variable selection methodology by selecting few predictors thus alleviating problems attendant to having many potential predictors compared to the number of observations.
Unfortunately, an evidence-based review identified relatively few predictors associated with clinically significant changes in the probability of weaning success or failure [ 2].
