Determination of the nature of growth of the main trends of time series in small quantity of observations


  • Poutko, Boris

    () (All-Russian State Distance-Learning Institute of Finance and Economics (ARDLIFE), Moscow)


The problem of determining the nature of growth in the short time series (an alternative choice between linear and exponential trend). We propose a simple criterion for selection. The result can be used, including in medicine, in particular, the interpretation of dynamics in the tumor marker
