This study explores the impact of maternal education and community characteristics on children's nutritional status using multiple regression analysis in a sample from Malawi. The results include coefficient estimation, model prediction evaluation, hypothesis testing, and checking for regression assumption violations.

Maternal education and community characteristics as indicators of nutritional status of children – application of multivariate regression Nutritional Status of Children
Main results • Step 1: Estimating the coefficients of the model(Table 10.2,10.3). • Step 2: Examining how good the model predicts(Table 10.4,10.5). • Step 3: Hypotheses testing. • Tests about the equation(Table 10.6,10.7). • Tests about individual coefficients(Table 10.8,10.9). • Part and partial correlation coefficients. • Step 4: Checking for violations of regression assumptions. • Checking normality of the errors(Table 10.10,Figure 10.1,10.2). • Checking for homogeneity of variance of the residuals(Figure 10.3,10.4).
