Impact evaluation ofwelfare actions over a community in Colombia, using a data correlated model
The impact evaluation of a communitarian program sometimes is based on statistical techniques such as linear regression models analysis when the goal is usually to quantify its effects on both social and welfare characteristics of a community. This involves the study of mental health and social vari...
