The TI-86 also does logistical regression. You can try your data there but
I have had similar kinds of errors in the past.
I have a beta version of the TI-89 and tried your data on it's logistic
regression. Avter over a minute, it gave the error message "singular
matrix". I do not know what the algorithm is for generating this equation
but your data sure doesn't like it!
Good luck.
