The phrase "analytical variable" is correct and usable in written English.
It can be used in contexts related to research, statistics, or data analysis where a variable is being examined or analyzed.
Example: "In our study, we identified the analytical variable that significantly influenced the outcome of the experiment."
Alternatives: "explanatory variable" or "dependent variable".
The N-TiO2 was examined by scanning electron microscopy (SEM) HITACHI-SU 6600 Analytical Variable Pressure FE-SEM with gold ion sputter, E-1020 microscope, operated at 20 kV in the secondary electron mode.
Thus, although the sampling frame allowed for a sample enriched for OP use, it was not used as an analytical variable.
Those with missing values on any analytical variable were excluded from analyses (60 respondents, 26%), resulting in a sample of 175 patients for the primary analyses (Fig. 1).
The effects of seven analytical variables including particle size, concentration of glycerol and HNO3 for stabilization and analyte extraction, respectively, the effect of ultrasonic agitation for slurry homogenization, concentration of chemical modifier, pyrolysis and atomization temperature were investigated by a 27−3 replicate (n = 3) design.
And the analytical variables of this method, such as accuracy, precision and interference factors, have been discussed.
It is found that both formulation and analytical variables can contribute to pharmaceutical HPLC assay bias using model compounds and formulations.
The use of a central composite design and the response surface methodology to determine the best conditions allows the optimum combination of analytical variables (pH, NaCl and extraction time) to be identified.
The analytical sample also excludes individuals with missing information in other analytical variables used as controls in the models (remaining N = 63 772).
Missing values on analytical variables have been imputed to the country-specific mean using the dummy-variable imputation method to avoid losing further observations (Allison 2002).
These indirect methods are based on the measurement of commonly used analytical variables (e.g. substrate and product concentrations, lumped biomass concentration) without requiring molecular techniques (Lopez-Vazquez et al. [2007]).
Of note, the combination of aβ2GPI, aPS/PT and LAC has demonstrated the best diagnostic accuracy for APS [4] and aPS/PT were recently recommended as a surrogate for LAC when specific inhibitors and/or analytical variables may affect its interpretation [5].
