... next step of our researches we have created seasonally adjusted series. If the seasonal component is removed from the original data, the re- sulting values are called the "seasonally adjusted" data. The original series can be adjusted by subtracting from it (additive models) or dividing it by (multiplicative models) the seasonal component. The resulting series is the seasonally adjusted series (i.e., the seasonal component will be removed). Figure 3 shows seasonally adjusted series of apartments' prices in Warsaw and Krakow. Figure 4 shows the fitting of the linear function for the studied time series. The value of determination coefficient is R 2 = 0,23 for Warsaw and R 2 = 0,21 for Krakow, which gives a low level of ...
... the time series of the average prices of apartments in Warsaw and Krakow in the period of 2006-2013 we can confirm the occurrence of sea- sonal fluctuations. Figure 3 shows the seasonal component in the time se- ries of the average prices of apartments in both analyzed markets Calculated seasonal components give information about the devia- tion of the real estate prices with the value resulting from the trend func- tion. The identified seasonal components for the transaction prices of apartments in Warsaw and Krakow in the period of 2006-2013 indicate that prices of apartments are subject to seasonal fluctuations. It was also shown that price decreases occur in the same quarters in Warsaw and Cracow. The other hand, it can be observed the time delay between price increases in Warsaw and Krakow with the size of a one ...
