LONGITUDINAL DATA ANALYSIS METHOD, COMPUTER PROGRAM AND CORRESPONDING SYSTEM

摘要

The method according to the invention for analyzing longitudinal data characterizing the evolution of at least a first variable as a function of at least one second variable, comprising steps for determining (22, 24, 26) adjacent variation sub-intervals for at least one of said first and/or second variables and characterizing (28) said data on said sub-intervals wherein the step for determining said sub-intervals comprises: defining (24) a representative function of a dispersion of said variable in said sub-intervals, the value of which depends on the lower and upper bounds of said sub-intervals, and determining (26) the lower and upper bounds of said sub-intervals optimizing the value of said function.
