The phrase "as a continuous predictor" is correct and usable in written English.
It can be used in statistical or research contexts where you are discussing a variable that is treated as continuous in analysis.
Example: "In our study, we analyzed age as a continuous predictor of health outcomes."
Alternatives: "as a continuous variable" or "treated as a continuous factor".
A General Linear Model with (1) mean heart rate as a continuous predictor, (2) snout-vent length and body mass at birth as dependent variables, and (3) embryo positioning and clutch of origin as categorical predictors yielded a marginally non-significant effect of embryo positioning F2, 38 = 3.11; P = 0.056 see Fig. 5).
Future analyses may look at more fine-grained comparisons of all of these participants using map scores as a continuous predictor of eye-movement variability.
We then compared the standard deviations using an analysis of variance (ANOVA) with year as a continuous predictor and disease as a random factor.
When modeled as a continuous predictor, a U-shaped relationship between systolic BP dipping ratio and future CAC was apparent and persisted after adjustment for multiple potential confounders (P<0.001 for quadratic term).
We took the absolute value of the difference between the mean log prevalence estimates and the actual log prevalence and performed ANOVA with year as a continuous predictor and disease as a random factor.
Six models were built, three for each definition considering three different cutoffs for lactate (as a continuous predictor, stratified at ≤2 or >2 mEq/L and at ≤4 and >4 mEq/L).
Serum urate was also entered as a continuous predictor into the models.
Thus, the probability of cancer status can be viewed as a continuous predictor and performance evaluated using ROC and AUC measures.
However, this fails to take into account the large disparity in the degrees of freedom (1 for species richness when it is treated as a continuous predictor versus 294 for species composition).
Finally, to test for a physiological trade-off between speed and endurance, we performed linear regressions within each ecotype and used an ANCOVA for speed in the second trial, with speed in the first trial as a continuous predictor and lake and ecotype as categorical predictors, as well as all the possible double interactions between these three terms.
In the case of local adaptation within regions (Experiment 2), plant and soil populations were fully reciprocal among populations, so that distance between plant and soil populations ('away soil') was used as a continuous predictor and local adaptation was tested from two perspectives (see above).
