Резюме: The research investigates the latent influence upon missing values (MV) appearance in Labour Force Survey conducted in Bulgaria 2007 by National Statistical Institute. In previous research [1] was shown that mechanism of MV is MNAR and after K-means clustering procedure the database was split in to two general clusters – Cluster 7 and the rest data. In this research specific analysis is focused on data excluded Cluster 7, and is performed exploratory factor analysis to extract general factors that described internal structure in database. The three variables v14, v22 and v25 (contained MV) are grouped in latent “missing” factor as the result of the initial factor analysis. Three mediation models are performed, using structural equation modeling (SEM) and confirmatory factor analysis, to explain the total, direct and indirect effect of the latent factors in database and variables with MV.
