Error with strucchange/breakpoints
Hi, I am trying to a strucutural change analysis on a certain data set. Attached here, with variable name "xcd" http://old.nabble.com/file/p26226190/xcd.rda xcd.rda Am using the following command: bp.inrz<-breakpoints(INR~SPX+WPI,data=xcd,h=26) But keep on getting this error whatever variables i put in on the x side as regressors: Error in chol2inv(qr.R(qr(X))) : element (3, 3) is zero, so the inverse cannot be computed Any insights...
