Review article

The article proposes a method for evaluating the growth rate of the real estate market, the method being derived from the joint normal law of distribution of price logarithms applied to cadastral value. Pricing factors are considered both as qualitative and continuous ones. Qualitative factors are used to divide sets of objects into clusters. Analysis of two-dimensional distributions of cadastral values and dependencies that are derived from them (including growth rates) is carried out for each cluster separately. The proposed method involves the use of large amounts of data, which do not allow applying the usual methods of testing statistical hypotheses immediately. A method of testing large two-dimensional samples for joint normality is proposed for the two-dimensional samples of cadastral (and market) values. All examples are based on a comparison of the results of cadastral valuation of built-in commercial real estate in St. Petersburg in 2015 and 2018.
