Abstract.

The main goal of this work is revision of different approaches and technologies which presents in such powerful language as SAS Base. Proposed some related examples of writing ETL procedures using PROC SQL, DATA STEP, MERGE for filtering and combining tables from different data sources. Paper presents methods for visualizing data using PROC GPLOT, identifying collinearity using Variance Inflation Factor, reduction of the list of the variables by the principal component analysis, identifying lag order of autoregression model. Repressors for task were obtained from the Kyiv Observatory through the processing of real satellite images for the period from 2003 to 2017.
