Hi, 
   
  I am trying to calculate the descretionary accruals using the bootstrapping technique with the R program, but I keep getting an error message.
   
  Previously, after typing in the command on the front sreen, R would return the output without any problems. I am now using a different dataset, and am getting the following error:
   
  Error in solve.default(t(X) %*% X) : system is computationally singular: reciprocal condition number = 3.48336e-17
   
  And the command I typed is:
   
  source("prog2.txt")
   
  I have checked my datafiles and the prog.txt files but everything appears to be in order. Do you know what this error refers to, or what I need to do to resolve the problem?
   
  Regards,
  Rutendo Kaviya
