The phrase "a crude estimation of" is correct and usable in written English.
It can be used when referring to a rough or imprecise calculation or assessment of something.
Example: "The scientist provided a crude estimation of the population size based on limited data."
Alternatives: "a rough estimate of" or "an approximate calculation of".
Second, because life expectancy is also a function of co-morbidity, performance states, and recurrence [ 23], the current estimates provide only a crude estimation of the average EYLL.
In particular, taking (k=1) in Theorem 1, we may immediately deduce a crude estimation of (S r)).
A crude estimation of the financial losses based on the number of icing hours and the number of installed MW is also proposed.
A crude estimation of BER can be performed by using a simple modulation and detection scheme, which is based on a baseband on-off keyed system as the one that illustrated by Barry et al. [9].
The parametric planning models have rather low complexity as they do not access the bitstream and utilize bitrate, codec type, and packet loss rate for making a crude estimation of video quality.
Finally, Müller's hypothesis on the use of acoustic flow by CF FM bats for obstacle avoidance is also implemented in RoBat, resulting in a crude estimation of the target's passing distance at small bearing angles, which improves as the angle increases, nevertheless sufficing for avoiding the two reflectors of the experiment.
This report on the characteristics of patients traveling to England from the Middle East and tested for MERS-CoV enables a first crude estimation of the positive predictive value of different signs and symptoms during the first year following the emergence of this pathogen.
Data on the prevalence used in this study were therefore derived from a crude estimation based on the number of the hearing disabled population and a few regional surveys.
Nevertheless, we attempted a crude estimation using the simplest, linear model of the increase in parallel changes depending on the depth of the tree.
A crude estimation using ξ=49 nm,R□,n=290 Ω, and B=3×10−5 T gives R□,v=6.3×10−2Ω, which is in the same order of magnitude as the observed value of approximately 2×10−2Ω.
A crude estimate of the participation rate, based on an estimation of the eligible population, has been calculated as 16% (Bonde et al. 1998).
