The phrase "approximation that is a" is correct and usable in written English.
You can use it when discussing a specific type of approximation in a mathematical or scientific context.
Example: "The approximation that is a linear function provides a simple model for understanding the data trends."
Alternatives: "estimate that is a" or "approximation which is a".
In this paper, we generalize Steinʼs method to "infinite-variate" normal approximation that is an infinite-dimensional approximation by abstract Wiener measures on a real separable Banach space.
The empirical claim is that all fundamental physical magnitudes and their state transitions are such as to be exactly described by an appropriate computational formalism — without resorting to the approximations that are a staple of standard computational modeling.
They also shared a certain humour - "Dear Thora, Just come up to change the lavatory seat, love Alan" read one of his postcards from Yorkshire - and a disdain for approximation: "That's an 'if', not a 'but', and when you do a Bennett it is an 'if', not a 'but'," she remarked about memorising his scripts.
When the results obtained above are used, a power-law dependence is obtained: 1 Of course, the replacement of lknot(A) with lknot(0) in the relationship l A ≈ lknot(A) is an approximation that is expected to break down precisely in the region of validity of this equality.
Instead, we approximated relative risks by calculating the odds ratios obtained from unconditional logistic regression models, an approximation that is reasonable for a rare disease such as brain tumour.
This strategy relies on the use of a non-conforming quadratic approximation that is defined on a sufficiently fine mesh.
Here, we developed a novel approximation that is extremely accurate for a population with a large effective size.
An initial-value problem is formulated with linear Boussinesq equations to study the inertio-gravity waves without the "traditional approximation" that is to include a complete effect of rotation.
The bivariate normal linear model on the logarithmic scale is an approximation that is used here because the data are positive data.
The resulting potential is a harmonic approximation that is much simplified than sophisticated potentials (Fig. 1a) used in NMA involving multiple bonded and nonbonded terms, which may or may not be harmonic depending on the instantaneous configurations of biomolecules in question.
