The phrase "actual variability" is correct and usable in written English.
It can be used when discussing the real or true differences or changes in data, measurements, or phenomena.
Example: "The study revealed actual variability in the results, indicating that the treatment had different effects on different subjects."
Alternatives: "real variability" or "true variability".
However, the hydrological implications of actual variability remain widely unknown since the required data are not easily collected.
The solution of the generalized interval eigenvalue problem is pursued by taking into account the actual variability and dependencies of uncertain structural parameters affecting the mass and stiffness matrices.
Different variabilities and uncertainties usually are lumped together and observed as the total variability, which includes both the actual variability of soil and rock properties and other knowledge uncertainties, such as measurement errors and statistical uncertainty.
It is the actual variability, not the total variability, which affects directly the observed performance (i.e., actual response) of geotechnical and geological systems and is of primary interest in site characterization.
This paper aims to consolidate recent advancement in Bayesian studies in site characterization and develops a Bayesian inverse analysis framework for direct quantification of the actual variability of various soil and rock properties.
The actual variability of the CNTs aspect ratio and the CNTs degree of dispersion are experimentally measured and introduced in the proposed model by averaging the Eshelby tensor over the actual CNT lengths distribution and by accounting for the effective CNT volume fraction.
Ensemble dispersion quantifies subscale velocity fluctuations between realizations, which overestimates the actual velocity variability.
Regarding the sensitivity, using the EMD method also outperforms in noisy conditions (0.57 compared to 0.46 for SNR=8 dB), while it decreases in noiseless conditions.Conclusions: The proposed test setting designed to analyze the performance guarantees that the actual physiological variability of the cardiac system is reproduced.
These people have rendered a service to humanity by emphasizing the overlooked role of chance in our lives, the WYSIATI phenomenon, pseudoreplication, the irresponsible adoption of short-cut statistics like chi-square and Kruskal-Wallis instead of measuring actual sample variability, and so on.
Here, we used the actual temporal variability of survival probabilities φ (see Results) to estimate the coefficients (mean a and variance b) of the function φ(t+1) = φ(t)·a +rand·b where t was the time (year), φ was the survival probabilities estimated in the previous CMR analysis and rand was a uniform distribution with range [0, 1].
However, the actual physiological variability, which could reach up 20 mmHg, is used to be ignored [ 8].
