8.  SIMPLE REGRESSION
MODEL :
y = a+bx+e
here one independent
and dependent
variables
 MULTIPLE REGRESSION
MODEL :
y =
a+b’x’+b2x2+bnxn+e
Here more than two
variables in which one
is dependent and
others are independent
variables

10.  Here mathematical equation is formed to predict
the value of unknown variable from given known
variables
 Least square method is mostly used model and
method of regression analysis

11.  R (-1 < 0< +1 )
 R SQUARE
 RESIDUAL ERROR (E)
 REGRESSION LINE

14.  SAS
