The idea of the current research stemmed from the vital role of investment in the development of sustainable human resources, as the research aims to investigate education as a mechanism for investment in human and intellectual capital in the College of Administration and Economics / University of Baghdad, which is a site for conducting the study, and highlights the importance of research through the flow of knowledge experiences of capital Intellectual and human money, which is the source of wealth and pillars of power. The problem of the research was represented by a major question: What is the extent to which the quality of education can be applied as a means of investing in intellectual and human capital? The case study approach was used because this approach is characterized by combining more than one method in the analysis, and a checklist was prepared for this purpose and presented to a group of academics in Iraqi colleges for arbitration

Abstract:
The models of time series often suffer from the problem of the existence of outliers that accompany the data collection process for many reasons, their existence may have a significant impact on the estimation of the parameters of the studied model. Access to highly efficient estimators is one of the most important stages of statistical analysis, And it is therefore important to choose the appropriate methods to obtain good estimators. The aim of this research is to compare the ordinary estimators and the robust estimators of the estimation of the parameters of
