Abstrakt EN: Paper presents a comparative macroeconomic analysis based upon GDP, inflation and stock exchange index time series of Visegrad countries within the period 1997Q1 till 2010Q4. Parametric representation of data in 3-D state space enables to tackle the macroeconomic development as a curve. Based upon differential geometry approach Frenet frames are constructed at selected set of discrete points along the curve. Investigation of frame translations provides both incremental and accumulated curve lengths, whereas frame rotations may generate traces on unit sphere. Numerical results together with corresponding macroeconomic interpretations of these quantities generated are discussed in detail, and computer implementation is presented, too.
