The phrase "a targeted class" is correct and usable in written English.
It can be used when referring to a specific group of individuals or entities that are the focus of a particular action, study, or initiative.
Example: "The research focused on a targeted class of consumers who are more likely to purchase eco-friendly products."
Alternatives: "a specific group" or "a defined category".
In this article, the allocation that minimizes the sum of the variances of the estimators of user's accuracy, producer's accuracy, and area of a single targeted class for a fixed total sample size is derived for stratified random sampling.
For example, the targeted class might be a rare land-cover type such as wetland or in the case of a land-cover change assessment forest loss.
Second, narrower targeting is likely to increase the employment effect for the targeted class because the demand for a small subset of the labor force is more elastic than the demand for a broader class of labor.
Pseudorandom generators (PRGs) are objects that take a short random seed, and stretches it to a much longer string that looks random to a targeted computation class.
We find that targeted class closure affords strong mitigation effects: closing a class for a fixed period of time – equal to the sum of the average infectious and latent durations – whenever two infectious individuals are detected in that class decreases the attack rate by almost 70% and significantly decreases the probability of a severe outbreak.
The targeted class closure strategy already yields a large reduction of the epidemic peak, and this reduction is only slightly improved by the targeted grade closure and whole school closure strategies (for the same closure durations).
Figure 1 shows the effect of closure duration for the targeted class and targeted grade strategies at a fixed closure-triggering threshold of 3 symptomatic cases.
The effect of the targeted class and grade closure strategies is similar to the case of a smaller β com : these strategies lead to a smaller and shorter epidemic peak with respect to the baseline strategy.
