The phrase "a more rigorous method" is correct and usable in written English.
You can use it when discussing an approach or technique that is more thorough or strict in its application compared to another method.
Example: "In our research, we decided to adopt a more rigorous method to ensure the accuracy of our results."
Alternatives: "a stricter approach" or "a more thorough technique."
A simplified proximate method and a more rigorous method incorporating a Langmuir isotherm approach failed to give accurate predictions.
But this needs to be combined with a more rigorous method for allocating resources only to where the prospects for success are greatest.
First a simple slope stability analysis is performed where emphasis is put on the comparison with a more rigorous method combining finite element modelling with stochastic modelling of soil behaviour, namely with random field theory.
It is finally shown that the electromagnetic response of the structure calculated with this numerical method is in good agreement with a more rigorous method such as the rigorous coupled wave analysis, whereas it requires a much lower computing power.
The use of a ruggedness study provides a more rigorous method for assessing method precision than a simple comparative intermediate precision study which is typically performed as part of method validation.
Designers need to consider the new capabilities afforded by these technologies in the context of current regulations and new operational concepts, which is why they need a more rigorous method by which to plan the introduction of advanced HSIs in NPP work areas.
One concern she raised about the study was that it simply looked back at records instead of using the more rigorous method of picking patients at random to compare types of screening.
In a previous paper (Sörensen et al. 2003) we validated the use of SUV measurements in human femoral allografts 40 min after tracer injection against the more rigorous method also employed by Foldager et al. The correlation over a wide range of metabolic activity was r = 0.97, indicating that SUVs and Gjedde-Patlak plots perform equally in this setting.
The last decade of research on diagnostic error has made promising steps and laid a foundation for more rigorous methods to advance the field.
Before the F.D.A. approves a new medicine, the drug must survive testing for safety and efficacy in a three-stage sequence of trials, each of them involving a larger sample and more rigorous methods.
However, there is a need to develop more rigorous methods for assessing the reliability of the estimated graph.
