- Richards growth model and viability indicators for populations subject to interventions Selene Loibel Marinho G. Andrade João B.R. do Val Alfredo R. de Freitas Multidisciplinaria (Ciencias Naturales y Exactas) population risk parametric estimate Richards growth model harvested populations likelihood profile function In this work we study the problem of modeling identification of a population employing a discrete dynamic model based on the Richards growth model. The population is subjected to interventions due to consumption, such as hunting or farming animals. The model identification allows us to estimate the probability or the average time for a population number to reach a certain level. The parameter inference for these models are obtained with the use of the likelihood profile technique as developed in this paper. The identification method here developed can be applied to evaluate the productivity of animal husbandry or to evaluate the risk of extinction of autochthon populations. It is applied to data of the Brazilian beef cattle herd population, and the the population number to reach a certain goal level is investigated. 2010 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32717686027 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.82
