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
