The phrase "a poor estimate of" is correct and usable in written English.
It can be used when discussing the accuracy or reliability of a calculation, assessment, or judgment regarding a particular value or situation.
Example: "The report provided a poor estimate of the project's total costs, leading to budget overruns."
Alternatives: "an inaccurate assessment of" or "a flawed calculation of".
Misspecification of these event rates may lead to a poor estimate of the necessary sample size.
However, neglecting the noise variance estimate altogether may lead to a poor estimate of the parameter vector.
Even with a poor estimate of pitch range, which is unavoidable in very low SNR conditions, the proposed algorithm improves the initial estimate during the iterative process.
However, for distributed microphone arrays in reverberant environments this phase compensation leads to a poor estimate of the actual phase differences.
It is worth to emphasize that a bad estimate of H may lead to a poor estimate of a, b and c.
A simple optimisation that neglects scattering between axial segments significantly overestimates the available attenuation and provides a poor estimate of the optimum segment lengths.
Due to the reduction in scenarios, the solution of LC-SB is less accurate, and it gives a poorer estimate of the standard deviation than of the mean value.
In the second type of written work, students made a poor estimate for the size of the first partition and then used that to make visually similar pieces.
However, these data also imply a surprising structure to the SNr microcircuit namely, even a relatively poor estimate of population activity (7 20 simultaneously recorded units across electrodes spread over hundreds of microns) is sufficient to provide predictive power for the response of individual units.
Importantly, we chose to standardise the infusion to intra-articular pressure as a set volume of infusion (for example, 60 ml) provides a relatively poor estimate of capsular tension due to large individual differences in both the size of the joint cavity and capsular elastance.
In other words, the current data on the number of condoms sold or distributed provide a very poor estimate of the actual number of condoms used.
