packet five concept map

1. assumption

   • mean=0
     • calculate CI for mean
   • normally distributed
     • looking for fitness through testing residuals
       • normal probability plot
       • histogram of residuals
       • fitted vs residuals
       • shapiro wilkes test
   • constant variance
     • as we move along x variance doesn't change
     • look at fitted vs residual and check for changes along x
   • indenpendent error
     • DW test
       • fitted vs residual look for pattern
       • 0-4 range positive to negative correlation 2 means uncorrelated
