Abstract

In the paper results of study on the influence of inadequate information on the estimation of survival curve using the Kaplan-Meier method will be presented. Authors carried out the time of being unemployed analysis for people unregistered from the District Labour Office in Szczecin in the IV quarter of 2006. Methods of survival analysis allowing censored data applying were used. In the described study these are the people that have been unregistered due to different than finding job reasons. In their case one can suppose that they took a job but did not report it to the office. This information may have essential influence to the course of survival curve describing probability of being unemployed (in register) for specific period of time.
