bug with boot.sw98 function (PR#8999)
...om: (NULL) (84.9.38.207) I'm using the FEAR library to perform Data Envelopment analysis with a 36,000 obs dataset. The function dea is working fine but then when I try to use the boot.sw98 to come up with some sensitivity analysis I get the following error: boot.sw98(XOBS=x,YOBS=y,NREP=100,DHAT=dhat,RTS=3,ORIENTATION=2) Error in 0:L : NA/NaN argument In addition: Warning message: longer object length is not a multiple of shorter object length in: kappam * Gcounts What does this mean? Is this because I have too many observations? What can I do to fix it? Please let me know if you...

Maximum likelihood estimation of a truncated regression model
Hi, I have a quick question regarding estimation of a truncation regression model (truncated above at 1) using MLE in R. I will be most grateful to you if you can help me out. The model is linear and the relationship is "dhat = bhat0+Z*bhat+e", where dhat is the dependent variable >0 and upper truncated at 1; bhat0 is the intercept; Z is the independent variable and is a uniform random variate between 0 and 1; and e is the error term. I realised that R doesn't have a built-in function to estimate truncated r...
