For J=l,...,16, should matrix No = 1-5 NIT(J) 15 



correction occur within Jth 6-10 

 pass through data? If so, is Correction with 

 intermediate output desired?Z / ' intermediate 



output = -A 



Correction without 

 intermediate output 

 = A 



NOTE: For passes J = 2,..., 16, if no additional passes through the data are desired, 

 NIT (J) is set equal to 9999.

— Matrix correction removes the effects of the (X'X) matrix used to start that pass 

 through the data from both the resulting (X'X) -1 matrix and the vector of regression 

 coefficients. Requesting matrix correction within a pass through the data reduces the 

 number of passes through the data required for convergence. However, experience has 

 indicated that frequently any savings in computations resulting from fewer passes 

 through the data are offset by increased computations arising from the additional 

 matrix inversions.
