The time and budget restrictions in survey sampling can impose limits on the area sample sizes. This may reduce the possibility to obtain area-specific and population parameters estimates with adequate precision. Market research companies and institutes for producing official statistics face frequently this problem. Various models and methods for small area estimation (SAE) have been developed to solve this problem. The sample allocation must support the selected model and method to ensure efficient estimation and must be implemented in the design phase of the survey. The proposed allocation is developed by incorporating auxiliary information, a model, and an estimation method. The estimated parameters are area and population totals. The performance of this allocation is assessed through design-based simulation experiments using real, regularly collected register data. Five other allocations selected from the literature serve as references. Model-based estimation is applied to two allocations and design-based Horvitz-Thompson and model-assisted GREG estimation to four model-free allocations. Four allocations are based on past register data. The allocation with uniquely best performance among all alternatives was not found, but the simulation study supports the comprehensive survey plan where the sampling design is conditioned on the available auxiliary information, selected model, and method. ...

Ecological and evolutionary consequences of selective interspecific information use Hämäläinen, Reetta; Kajanus, Mira, H.; Forsman, Jukka, T.; Kivelä, Sami, M.; Seppänen, Janne‐Tuomas; Loukola, Olli, J. (Wiley, 2023)Recent work has shown that animals frequently use social information from individuals of their own species as well as from other species; however, the ecological and evolutionary consequences of this social information use ...
Is it interspecific information use or aggression between putative competitors that steers the selection of nest-site characteristics? A reply to Slagsvold and Wiebe Forsman, Jukka T.; Seppänen, Janne-Tuomas; Mönkkönen, Mikko; Thomson, Robert L.; Kivelä, Sami M.; Krams, Indrikis; Loukola, Olli J. (Wiley-Blackwell Publishing Ltd., 2018)A growing number of studies have demonstrated that heterospeciﬁc individuals with overlapping resource needs – putative competitors – can provide information to each other that improves the outcomes of decisions. Our studies ...
Observed Fitness May Affect Niche Overlap in Competing Species via Selective Social Information Use Loukola, Olli; Seppänen, Janne-Tuomas; Krams, Indrikis; Torvinen, Satu; Forsman, Jukka (University of Chicago Press, 2013)Social information transmission is important because it enables horizontal spread of behaviors, not only between conspecifics but also between individuals of different species. Because interspecific social information use ...
The past and the present in decision-making : the use of conspecific and heterospecific cues in nest site selection Kivelä, Sami M.; Seppänen, Janne-Tuomas; Ovaskainen, Otso; Doligez, Blandine; Gustafsson, Lars; Mönkkönen, Mikko; Forsman, Jukka T. (Ecological Society of America, 2014)Nest site selection significantly affects fitness, so adaptations for assessment of the qualities of available sites are expected. The assessment may be based on personal or socialinformation, the latter referring to the ...
