The phrase "and a weak coefficient" is correct and usable in written English.
It can be used in contexts related to statistics, mathematics, or any field where coefficients are discussed, particularly when describing the strength of a relationship or effect.
Example: "The model showed a significant relationship between the variables, but it was characterized by a weak coefficient, indicating a less reliable prediction."
Alternatives: "and a low coefficient" or "and a feeble coefficient".
This model had a weak coefficient of determination (R2 (adjusted) = 0.3819).
In each instance, there was a significant P-value but a weak coefficient of determination (r).
However, each of the telomere-associated protein mRNAs also had a weak coefficient of determination (r).
The agreement was much better when compared with the International Telecommunications Union Radio communication Study group 3 digital maps with correlation coefficients varying from 0.84 to 0.98 in 23 locations; however there were negative correlation coefficient (of 0.2 in 7 stations) in the Middle Belt and a weak positive coefficient (of 0.09 in 6 stations) in the South South.
Then, as we can see in Fig. 11, there is no meaningful correlation between porosity and permeability in the studied well and a weak correlation coefficient (R 2) stands for these two parameters.
The P-values indicate there is a statistically significant association between levels of the telomere-associated proteins' mRNAs and TC, while the weak coefficient of determination indicates a single variable alone cannot predict TC entirely.
The only exception is VOLA, which shows a contradictory, albeit weak, coefficient in the basic model.
In this paper, we introduce a new geometric coefficient that is a related García-Falset coefficient and a weak∗ fixed point property, written (R^{ast} ( X^{ast},a ) ).
45 We found a moderate positive correlation between GP consultation rate and mortality (Pearson coefficient 0.42) and a weak positive correlation between LTC and mortality (Pearson coefficient 0.20) which suggests that provision is weakly associated with need rather than service standards.
In the high temperatures range, the nanowires exhibit a positive temperature coefficient of resistance and a weak temperature dependence.
