INTRODUCTION TO LINEAR REGRESSION

INTRODUCTION TO LINEAR REGRESSION

1. Definitions of Center

   • Central trend
     • Equilibrium distribution point

2. Smallest Absolute Deviation

   • Sum of different absolute deviations

3. Smallest Squared Deviation

   • Sum of different squared deviations
     • minimize the sum of
       • Deviations

4. Median

   • Midpoint of a distribution
     • Arithmetic median
     • Medium and fashion
       • Balance point on a balance
         • Minimize values
     • Symmetry
       • It allows
         • The median and mean are equal

5. Mode

   • Value that
     • It happens more often
       • Continuous variables
