The phrase "approximation of the early" is grammatically correct and can be used in written English.
It can be used in contexts where you are discussing a rough estimate or representation of something that occurred in the early stages of a process or event.
Example: "The approximation of the early results suggests that we may need to adjust our methodology for more accurate outcomes."
Alternatives: "estimate of the early" or "rough calculation of the early".
While this assumption can generally be considered as a good approximation to describe the early phase of an outbreak, more complicated seeding events may occur that would require numerical approaches able to explicitly take into account the initial conditions and assess the epidemic risks.
Rather, there's a sense of encountering incomplete or stock-level work: perhaps a discarded germ for something that long ago became something better, or a kind of paler approximation of an early Sabbath riff, good enough for the job at hand.
For achieving an approximation of the system properties in an early design phase including second order and parasitic effects a complex model of the whole system is derived.
An alternative approach, based on the so-called structural approximation of the model suggested in an early paper by [19], was proposed by [2] to avoid to sample a continuous state in the backward pass.
The resulting form of the distortion corresponds to made earlier approximation of the symmetrized strain (see, section Methods).
As an alternative to mesh refinement, an adaptive approximation of the growing delamination was obtained in earlier work by enriching the elements in the fracture process zone.
These results suggest that exposure assessment at the residential address at birth may be a good approximation of perinatal and early childhood exposure.
Billy Howerdel, the guitarist who writes the band's music, layered chiming chords in slow arpeggios in an approximation of early choral music.
As argued earlier, the CFO estimator of (13) or (14a) is an approximation of the first order level.
History is always just an approximation of the past.
