The phrase "approaches for fitting" is correct and usable in written English.
It can be used in contexts where you are discussing methods or strategies for fitting something, such as data models or physical objects.
Example: "We explored various approaches for fitting the model to the data to improve accuracy."
Alternatives: "methods for fitting" or "strategies for fitting".
Four separate approaches for fitting the da/dt data to determine the derived constants C and m are evaluated.
2/14/2014: This page provides a new paper, software tools and a tutorial video describing approaches for fitting fragility functions to structural analysis data.
We used Bayesian approaches for fitting quantitative genetic models (Nakagawa and Schielzeth 2010).
We explain and exploit the equivalence of N-mixture and multivariate Poisson and negative-binomial models, which provides powerful new approaches for fitting these models.
We pointed out that empirical approaches for fitting models to organ growth and development may be used to inform horticultural or conservation questions of other rare cycad taxa.
However analysis techniques for stochastic models have tended to lag behind their deterministic cousins due to the heavier computational demands of the statistical approaches for fitting the models to experimental data.
A computational approach for fitting sedimentation velocity experiments from an analytical ultracentrifuge in a model-independent fashion is presented.
In particular, we propose an original approach for fitting a pre-defined parametric shape model to depth data by exploiting the 3D body pose tracked through a sequence of range maps.
In this paper, we use the design approach for fitting the proportional hazards (PH) model and prove formally the asymptotic normality of the sample maximum partial likelihood (SMPL) estimators under the PH model for both stochastically independent and clustered failure times.
Edwards's method is a widely used approach for fitting a sine curve to a time-series of monthly frequencies.
