The phrase "a rigorous method of" is correct and usable in written English.
It can be used when describing a systematic and thorough approach to a particular process or study.
Example: "The researchers employed a rigorous method of data collection to ensure the accuracy of their findings."
Alternatives: "a strict approach to" or "a thorough technique for".
We also present a rigorous method of computing the Fréchet derivative using the adjoint operators.
This is a result of the poor understanding of the chemistry involved and a lack of a rigorous method of modelling, design and scale-up.
Coupling a 3D Computational Fluid Dynamics (CFD) tool with a rigorous method of decision making is becoming indispensable in the design process of complex systems, as internal combustion engines.
Because we used a raster scan method for these measurements, the acceleration and deceleration provided a rigorous method of measurement.
Science is able to achieve its results by following a rigorous method of investigation involving the creation and testing of hypotheses against observational evidence.
From the outset, Bernoulli wished for his work to demonstrate that combinatorics and probability theory would have numerous real-world applications in all facets of society in the line of Graunt's and de Witt's work— and would serve as a rigorous method of logical reasoning under insufficient evidence, as used in courtrooms and in moral judgements.
This paper postulates a rigorous method for the construction of classical planning domain models.
The development of ADAS Advance Driver Assistance Systemss) increasing security of the driver implies the use of a rigorous method for their design and evaluation.
An SRS presented without any temporal information makes creating a corresponding acceleration time history for an experimental or numerical study prohibitively difficult without a rigorous method to determine an inverse of the SRS (a corresponding time history).
Authors in [21] have developed a rigorous method for assessing the reliability of estimated data coefficients.
Reitsma and others [ 12] proposed the direct analysis of sensitivity and specificity estimates using a bivariate model BM, which yields a rigorous method for the meta-analysis of data on diagnostic test accuracy, in particular when the studies are selected based on a common threshold [ 16].
