The phrase "a more formal test" is correct and usable in written English.
It can be used when discussing the need for a test that adheres to stricter standards or protocols, often in academic or professional contexts.
Example: "To ensure the accuracy of our findings, we decided to conduct a more formal test of the hypothesis."
Alternatives: "a stricter assessment" or "a more rigorous evaluation."
There are common sense ways of assessing our own intelligences, and if it seems appropriate, we can take a more formal test battery.
Specifically, a new "side function", to determine the relative position of the particle and the cell, was introduced to build a more formal test process.
A more formal test of the assumption is possible (see Armitage and coworkers [ 2]).
However, the very nature of risk estimates (estimated probabilities) allows their use as a likelihood function to do a more formal test of adequacy.
For a more formal test, we intercrossed hitchhiker with the Smo-targeted null allele (63) to test for dependence on Smoothened, an obligate component of all hedgehog signalling.
For a more formal test of when regional means deviated significantly from the overall mean, we used the χ test, because the data were binomially distributed.
Further fractionation of PD into its constituent membrane components (ER, PM and membrane rafts) would be a feasible practical strategy for more formal testing of these hypotheses.
This would exclude a substantial proportion of children who would have to return for testing, and subsequently, only the subset of children with glucose levels surpassing specified thresholds of either nonfasting test would then have to undergo more formal testing with an FPG or a 2-h OGTT to confirm the diagnosis.
For example, design teams at Gap Inc. test early and often, typically recruiting employees from the "Gapateria" (the cafeteria at corporate headquarters) to run quick tests on concepts before taking them into more formal tests and experiments in a usability lab, online, or in retail stores.
While PCA and ADMIXTURE provide a useful visualization of the data, we also performed more formal tests for admixture.
More formal tests of randomness are notoriously tricky.
