The phrase "analyzed by fitting" is correct and usable in written English.
It can be used in contexts related to data analysis, statistics, or modeling where fitting a model to data is involved.
Example: "The results were analyzed by fitting a linear regression model to the dataset."
Alternatives: "assessed through fitting" or "evaluated using fitting".
Adsorption data were analyzed by fitting with Langmuir and Freundlich adsorption isotherms.
Combustion phasing was also analyzed by fitting different probability density functions (statistical distributions).
The THz spectra were analyzed by fitting with the dielectric function model proposed by Brendel.
Adsorption data were analyzed by fitting with Langmuir, Freundlich and Temkin adsorption isotherms.
XANES spectra were analyzed by fitting with a combination of Lorentzian and arctangent functions, which simulate the resonance peak and the absorption edge step, respectively.
Many engineered components can be analyzed by fitting primitives to the point cloud using nonlinear least-squares minimization.
The kinetic experimental data were analyzed by fitting the data to the pseudo-first-order and pseudo-second-order models.
The existence of multiple QTL on the same linkage group was also analyzed by fitting a two-QTL model to the analysis.
The relationship between refractive index and composition was analyzed by fitting the experimental data to different theoretical models for the refractive index of mixed films.
In this work, temporal profiles of 18 solar energetic particle events have been analyzed by fitting a pulse function to them in order to find a set of parameters which can be used to characterize the events.
Impedance spectra were analyzed by fitting an equivalent circuit, which modeled: the ionic conductivity, the dielectric constant, the electric polarization due to inhomogeneity in the bulk of sample and the electrode polarization.
