The phrase "area of variability" is correct and usable in written English.
It can be used in contexts discussing statistics, research, or any field where variability is a factor that needs to be addressed or analyzed.
Example: "In our study, we identified the area of variability that significantly impacted the results."
Alternatives: "range of variability" or "scope of variability".
Each area of variability included a set of final factors.
The objects were also represented by their projections and area of variability through correlation studies using principal component analysis (PCA).
For example, the review of the literature carried out by Sculpher et al. shows that four groups are generally retained as the area of variability: the characteristics of the patients, the clinical parameters, the healthcare systems, and the socio-economic aspects [ 4].
Additional file 3: The values of the CTR α (j ) for the areas of variability (variables).
Figure 3 shows the areas of variability (variables) in the correlation circle.
To perform PCA, we began with the matrix X m,n ), where m corresponded to the 12 objects (i.e. observations or individuals in statistical terms) and n to the 16 areas of variability (i.e. the variables).
Effective implementation of PHM strategies requires accurate identification of at-risk patients and key areas of variability in care.
A detailed knowledge covering the large areas of variability, which characterize forest biomass and biophysical structure, the properties and the state of evolution of vegetation, is frequently critical given that it requires significant campaign operations in terms of time/operator and cost (Chen et al. 2007; Popescu 2007; Wallerman and Holmgren 2007).
The obtained sequences were aligned with 18S sequences found in GenBank and areas of variability were used to design probes.
The identification of the factors of variability and their regrouping into homogeneous categories (i.e. areas of variability) has already been studied in the literature.
Other areas of variability (e.g. quantity of external consultations (area 4)) were too close to the center to be interpretable.
