Kasvutempoon
Kasvutempoon is a concept used in growth modeling to quantify the pace at which a quantity increases over time. The term is Finnish for growth tempo, reflecting its function as a measure of how fast something grows, independent of its current size.
It is defined as the instantaneous relative growth rate: g(t) = d/dt ln X(t) = (1/X) dX/dt, where
Interpretation follows standard growth theory. If g(t) is constant, X grows exponentially. If g(t) increases, growth
Calculation for empirical data can be done in discrete time. A common estimate is g_t ≈ [ln X_t
Applications and limitations: Kasvutempoon is used in demography, ecology, economics, and epidemiology to compare growth patterns
