  The solar neutrino data are analyzed in a frequentist framework, using the
Crow-Gardner and Feldman-Cousins prescriptions for the construction of
confidence regions. Including in the fit only the total rates measured by the
various experiments, both methods give results similar to the commonly used
Delta chi^2-cut approximation. When fitting the full data set, the Delta
chi^2-cut still gives a good approximation of the Feldman-Cousins regions.
However, a careful statistical analysis significantly reduces the
goodness-of-fit of the SMA and LOW solutions.
  In the addenda we discuss the implications of the latest KamLAND, SNO and SK
data.
