The phrase "adequate approximation of the" is correct and usable in written English.
It can be used when discussing a measurement, estimate, or representation that is sufficiently close to a desired value or concept.
Example: "The model provides an adequate approximation of the actual data, allowing us to make informed predictions."
Alternatives: "satisfactory estimate of the" or "sufficient representation of the".
Based on existing products core time drivers based on features are successively identified until an adequate approximation of the time for the current product is achieved.
The results obtained confirmed an adequate approximation of the actual wind speed series and a significant improvement of the forecasting accuracy of the proposed model.
To confirm if the selected model provides an adequate approximation of the real system, the normal probability plots of the studentized residuals and diagnostics are provided by the Design Expert 6.0.7 software.
A quadratic polynomial model was developed for predicting the glucose conversion and the fitted model provided an adequate approximation of the true response as verified by the analysis of variance (ANOVA).
Ljung and Box [23] argued that the chi-squared distribution does not provide an adequate approximation of the distribution of the Q-statistic under the null hypothesis for short time-series, while Davies et al. [11] provided empirical evidence to support this argument.
It was therefore considered an adequate approximation of the underlying pharmacology.
A numerical 3D finite difference code is employed to identify adequate approximations of the distribution of normal stresses along the failure surface, with results showing that linear stress distributions along the failure surface are needed to obtain improved results in the case of weaker rock masses.
SB is most efficient and effective if the following assumptions are satisfied: (i) second-order polynomials are adequate approximations of the input/output functions implied by the simulation model; (ii) the signs of all first-order effects are known; and (iii) if two inputs have no important first-order effects, then they have no important second-order effects either (heredity property).
Heuristic solution procedures can generate adequate approximations of the set of efficient solutions to complex problems in reasonable time.
The goal is to achieve an adequate approximation of process outputs corresponding to the normal behaviour of the plant.
Results show that the model provides an adequate approximation of grain size distributions, satisfying the requirements of a cumulative distribution function.
