If a given class and feature value never occur together in the training data, then the frequency-based probability estimate will be zero.

This is true regardless of whether the probability estimate is slightly, or even grossly inaccurate.

Some researchers have suggested that perceived causes or reasons for an event, rather than imagery of the event itself, influence probability estimates.

Spider-Man knew that Palminetti's probability estimates were always uncomfortably close to the mark.

It would overstate the quality of our estimates to interpret this as providing precise probability estimates.

This statistic assumes that the current rates upon which the probability estimates are based will remain constant over the child's lifetime.

Both types of probability estimates are reported in this paper.

Ten-year probability estimates are largely influenced by the age in which they are conditioned.

There is a similar probability estimate for the strong Lucas probable prime test.

However, in reality accurate probability estimates are either unavailable or too expensive to gather.
