The phrase "ancillary variables" is correct and usable in written English.
It is typically used in research or statistical contexts to refer to additional variables that are not the primary focus but may still have an impact on the results.
Example: "In our study, we examined the main factors affecting performance, while also considering the influence of ancillary variables such as age and education level."
Alternatives: "secondary variables" or "supplementary variables".
These methods usually infer the fine-scale variability in soil moisture using variations in ancillary variables like topographic attributes that have relationships to soil moisture.
The model captured the variability in emergency department visits due to several factors by including nine ancillary variables in addition to wildfire PM concentration.
The data dictionary for all indicators and ancillary variables are accessible via the data set landing page.
A rule-based model was fitted to identify the influence of drainage and ancillary variables.
A second is the use of a simple predictive linear model of the target soil property on the ancillary variables.
Further researches of methods combined with ancillary variables are needed to be implemented to improve the interpolation performance.
The second is a fuzzy variogram for topsoil organic carbon content in a field, based on the crisp variogram of a related ancillary variable and generalized information on topsoil variability at field scales.
Here we proposed the variance quadtree algorithm for sampling in an area with prior information represented as ancillary or secondary environmental data, and the covariance structure of the ancillary variable is non-stationary.
Therefore, the plot-ID corresponding to the imputed aboveground tree biomass reference observations mapped by [29] was itself mapped as an ancillary variable for this study.
Table 6 AP2 summary table: SW T was used as ancillary variable to estimate the SW NC or the SW C input data Approach (a) (b) (c) (d) Eq. (6) Eq. (6) + difference Eq. (6) + Const.
Therefore, the plot-ID corresponding to the imputed aboveground tree biomass reference observations mapped by [ 29] was itself mapped as an ancillary variable for this study.
