It is important to distinguish between two types of populations: the survey population and the target populations.
For both types of populations, there is also increasing interest to detect fainter objects corresponding to the small end of the size distribution.
Simple weighted averages calculated from a single study sample may be used to assess variability in accuracy in different types of populations.
There are places in the world where the infrastructure is not there and the resources are not there to send people door to door and gather [census] data, [but where] having an understanding of the different types of populations that live in your country would be very helpful.
Two types of populations were studied: homogenous (0, 100%) with all pen members presenting the same marked (M) or unmarked (U) phenotype, and heterogeneous (30, 50, and 70%) were the two phenotypes (M and U) coexisted in the same pen.
We describe and discuss, in particular, the application of this system for the analysis of behavior and interest of visitors in different types of populations and visits: on-site/ad-hoc (exhibitions, museums, cultural events) and territorial (historical downtown, archaeological or other touristic areas and routes including cultural resources).
"Traditionally, we've made technology for all types of populations, but industrial workers have been left behind.
Prevalence rates differed in different types of populations (Kruskal-Wallis P = 0.001).
Nevertheless, both types of populations are useful to study the genetic structure underlying disease, providing direction to the investigation of susceptibility genes and genetic pathways.
In this paper we propose a finite difference implicit scheme to solve fractional-order HIV model containing four types of populations: uninfected CD4+ T-cells, latently infected, actively infected CD4+ T-cells and HIV virus particles.
In the following we will explore three examples drawn from our empirical material where we think that biobanking practices are giving rise to the construction of different types of populations.
