The phrase "approximation changes" is correct and usable in written English.
It can be used in contexts where you are discussing modifications or variations in estimates or approximations.
Example: "The approximation changes significantly when we consider additional variables in the equation."
Alternatives: "estimation variations" or "approximate adjustments".
In the Oberbeck-Boussinesq approximation, all changes in the fluid properties due to temperature variations are neglected except for the change in density that gives rise to a buoyancy force g.
This is obviously an approximation because changes in the primary structure of a protein often lead to non-detectable (phenotypic) variations of morphological or physiological attributes.
Due to data limitations, the descriptive analyses can make only a rough approximation of changes in client volume over the study period.
The S sp method might be a good and simple choice for solving problems where approximation of changes in size distribution and number is necessary.
First, long-term conditions were characterised by their variability, which meant that a single rating could only ever be a crude approximation to changes over time.
NIRS is able to determine μa by the diffusion approximation or changes in μa by the modified law of Lambert and Beer if the optical path length and geometrical properties are known.
If the internet has taught us anything, it's that real change – or at least "raising awareness", the closest approximation to change we have in 2015 – comes from soaring string soundtracks and cloying poems about going outside.
Simple approximations for changes in disposition during pregnancy for both oseltamivir and oseltamivir carboxylate were predicted using compartmental approaches, as described in Donald Mattison's presentation.
For a first order approximation of the changes in the passive properties of L5 pyramidal neurons with addition of the excitatory solutions, we constructed current-voltage relationships of the neurons using hyperpolarizing current pulses.
Conceptually, this regression-based approach appears to be a reasonable strategy to provide at least some first approximation of the changes in confounding associated with the correlated variables, but the strict accuracy of this approximation is unclear.
