Avaliação de Imóveis por análise de regressão linear múltipla no bairro de Casa Forte, Recife/PE

Abstract

The objective of this work is to determine a mathematical model that represents the value of supply of apartments in the neighborhood of Casa Forte, in Recife / PE, based on the requirements of ABNT NBR 14653-2 (2011), through the survey of market data of properties, identification and selection of significant variables observing the requirements and methods established by the aforementioned technical standard, proposition and statistical validation of the developed mathematical model. The model presented a correlation coefficient of 0.954, showing a very strong linear dependence between the variables, with an adjusted coefficient of determination of 0.905, demonstrating that approximately 91% of the evaluation value is explained by the selected variables. Statistical validation of the model was performed through the coefficient of determination and tests and analysis of linearity, normality of residues, homoscedasticity, autocorrelation and collinearity, observing the most stringent requirements established by the mentioned technical standard. The proposed model presented strong predictive power, adjusting very well to the collected data, with confidence interval presenting total amplitude less than 30%.
