Open file Poverty.sta
  • Open
    • Advanced linear/non-linear models

-> General linear models

-> Simple regression

  • Study the influence of POP_CHNG on PT_POOR. Review “Significance of all effects”. Via

More results -> Summary-> Coefficients,

review the coefficient of linear regression and intercept. Note beta coefficient, identical to Pearson correlation by absolute value.

  • Close the simple regression analysis window. Open Multiple regression.
  • Study the influence of all the 6 variables on PT_POOR.
  • Review the coefficients and confidences. Note insignificant values.
  • Perform residual analysis.
  • Perform several stepwise analyses. Find the optimal configuration.
