O Método dos Mínimos Quadrados (MMQ) e suas aplicações no ajuste de curva: relação entre casos confirmados e casos notificados de COVID-19 no município de Barra do Corda – MA

Abstract

This work is the result of a project that aimed to study the relationship between the number of confirmed cases daily accumulated versus the number of notified cases also daily accumulated, and to module this relationship using the Least Squares Method (LSM). It was realized in a town named Barra do Corda in the state of Maranhão - Brazil. A prior study of some aspects of Covid-19 will be carried out in order to contextualize and understand the characteristics of the disease, transmission and data collection. In addition it will be discussed the importance of mathematic modeling for decision making, involving the solving of the problem as in the containment of the pandemic, for instance. The data present in this analysis were generated and made available through reports which were also made available by the city health department of Barra do Corda. To understand the choice of this method, its development and applicability in the problem, it will be performed a previous theoretical study that involves mathematical contents such as vectors R, matrices and linear systems. Computational tools will be used in the construction of the data dispersion diagram as well as in the resolution of the method. The data collected and the results obtained, will be discussed and analyzed at the end of the project.
