It was confirmed by the constructed zero-one multiple regression model consisting of nine predictors. Multiple R2 of this model was 0.96. Additionally, the model was used to forecast the price of 1 m2 of usable floor area of a residential building completed in Poland on a quarterly basis for 2021. The last stage of the research was to evaluate the forecast obtained by calculating the MAPE index.
