"weaker estimate" is correct and usable in written English.
You can use it when you are comparing the accuracy of estimates. For example, "The newer estimate of sales was a weaker estimate than the original forecast."
In the latter case, cosψ achieves its maximum (=1) interior to the interval ( ψ 1, ψ 2 ), and the indicated procedure yields instead the slightly weaker estimate ( sin ψ 2 − sin ψ 1 ) 2 4 B − 2 ( 1 − cos ψ 2 ) < B U 0 2 < ( sin ψ 2 − sin ψ 1 ) 2 4 B. (5.2b).
Our somewhat weaker estimate of this association relative to others [ 32] may reflect our shorter follow-up time, choice of comparison (reference) group and more functionally impaired sample.
Conversely, the results show that the MTS criterion provides weaker estimates compared to the MS criterion.
The JMA assessed Sarah to have been somewhat weaker, estimating peak ten-minute sustained winds of 150 km/h (90 mph) along with a barometric pressure of 950 mbar (hPa; 28.05 inHg).
This temporal analysis suffers from the difficulty of the likely weaker estimates of the eye movement measurements during the hazard sequence because they only make up a smaller percentage of the film sequence.
Excluding these weaker estimates removes the flat tail.
Similar patterns, albeit weaker estimates, were observed for 8 and 9 hour sleepers.
Prenatal exposure to ETS was positively associated with the risk of infections, whereas postnatal exposure had a weaker estimated impact.
For an E. coli site which is estimated to be a strong binding site, the vast majority of mutations will result in a weaker estimated binding energy.
For the extreme case (p=1/(1+beta)), a weak estimate is given.
Instead of the boundedness in the extreme case, a weak estimate for ([b,H]) is showed.
