Resumo: | The purpose was defined to adjust different non-linear models in the analysis to death data by COVID-19 in Pernambuco and Ceará and to extrapolate the deaths numbers through forecasts. In this report, we analyze the official epidemic data available by the Ministry of Health of Brazil (MS), referring to the period of 25/03/2020 to 11/05/2020 for Pernambuco - PE and in the period of 26/03/2020 to 11/05/2020 for Ceará, of the deaths numbers, COVID-19 confirmed. For the comparison between the models, the adjusted coefficient of determination (), residual mean squares (RMS), and Akaike information criterion (AIC) were used. All models had good adjustments, with values of approximately 99%. The verification of the assumptions of the residues was carried out through graphic analyzes, and the assumptions were met. The cumulative deaths’ numbers in the period from 12/05/2020 to 10/10/2020 was calculated for Pernambuco and 12/05/2020 to 11/10/2020 for Ceará, in addition to the extrapolation of the absolute growth rate (AGR) for the respective intervals. The analyzes indicated that the inflection points of all models occurred within 200 days after the start of the pandemic. However, it is not yet possible to make reliable projections of when the numbers of confirmed deaths will minimize. Regardless of the possible uncertainty of the models' prediction, our observations indicate that the next few days may be critical in determining the future growth of death cases. |

En este informe, analizamos los datos de epidemia oficiales disponibles por el Ministerio de Salud de Brasil (MS), en referencia al período del 25/03/2020 a 11/05/2020 para Pernambuco - PE y en el período del 26/03/2020 a 11/05/2020 para Ceará, de las cifras de muertes, confirmó COVID-19. Para la comparación entre los modelos, se utilizaron el coeficiente de determinación ajustado (), los cuadrados medios residuales (RMS) y el criterio de información de Akaike (AIC). Todos los modelos tuvieron buenos ajustes, con valores de aproximadamente el 99%. La verificación de los supuestos de los residuos se llevó a cabo mediante análisis gráficos y se cumplieron los supuestos. Los números de muertes acumuladas en el período del 12/05/2020 a 10/10/2020 se calcularon para Pernambuco y 12/05/2020 a 11/10/2020 para Ceará, además de la extrapolación de la tasa de crecimiento absoluta (AGR) para los respectivos intervalos. Los análisis indicaron que los puntos de inflexión de todos los modelos ocurrieron dentro de los 200 días posteriores al inicio de la pandemia. Sin embargo, aún no es posible hacer proyecciones confiables de cuándo se minimizará el número de muertes confirmadas. Independientemente de la posible incertidumbre de la predicción de los modelos, nuestras observaciones indican que los próximos días pueden ser críticos para determinar el crecimiento futuro de los casos de muerte.Objetivou-se ajustar diferentes modelos não lineares na análise a dados de óbitos por COVID-19 nos estado de Pernambuco e Ceará e fazer extrapolações do número de óbitos por meio de previsões. Neste relatório, analisou-se os dados oficiais epidêmicos disponibilizados pelo Ministério da saúde do Brasil (MS), referindo-se ao período 25/03/2020 a 11/05/2020 para o estado de pernambuco - PE e no estado do Ceará no período de 26/03/2020 a 11/05/2020 do número de óbitos confirmados por COVID-19. Para a comparação entre os modelos empregaram-se o coeficiente de determinação ajustado (), quadrado médio dos resíduos (QMR) e critério de informação de Akaike (AIC). Todos os modelos tiveram bons ajustes, com valores de aproximadamente 99%. A verificação dos pressupostos dos resíduos foi realizada por meio de análises gráficas, e os pressupostos foram atendidos. Calculou-se o número acumulado de mortes no período de 12/05/2020 a 10/10/2020 para o estado de Pernambuco e 12/05/2020 a 11/10/2020 para o estado do Ceará, além da extrapolação da taxa de crescimento absoluto (TCA) para os respectivos intervalos. As análises indicaram que os pontos de inflexões de todos os modelos ocorreram dentro do período de 200 dias após o início da pandemia. Entretanto, não é possível ainda fazer projeções seguras de quando os números de casos confirmados de óbitos minimizarão. Independentemente da possível incerteza da previsão dos modelos, as observações indicam que os próximos dias podem ser críticos para determinar o crescimento futuro dos casos de óbitos.Research, Society and Development2020-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/455110.33448/rsd-v9i7.4551Research, Society and Development; Vol. 9 No. 7; e602974551Research, Society and Development; Vol. 9 Núm. 7; e602974551Research, Society and Development; v. 9 n. 7; e6029745512525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4551/3988Copyright (c) 2020 André Luiz Pinto dos Santos, Marcela Portela Santos de Figueiredo, Tiago Alessandro Espínola Ferreira, Frank Sinatra Gomes da Silva, Guilherme Rocha Moreira, José Eduardo Silva, Jucarlos Rufino de Freitasinfo:eu-repo/semantics/openAccessSantos, André Luiz Pinto dosFigueiredo, Marcela Portela Santos deFerreira, Tiago Alessandro EspínolaGomes-Silva, FrankMoreira, Guilherme RochaSilva, José EduardoFreitas, Jucarlos Rufino de2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4551Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:22.296248Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
