Description
The de.Finetti.Game function estimates the interval of a
subjective probability regarding a possible event in the near future.
Usage
1
Arguments
width
This is the maximum acceptable width of the interval for
the returned subjective probability. The user must specify a width
between 0 and 1.
Details
This function is a variation on the game introduced by de Finetti,
who is one of the main developers of subjective probability,
along with Ramsey and Savage. In the original context, de Finetti
proposed a gamble regarding life on Mars one billion years ago.
The frequentist interpretation of probability defines the probability
of an event as the limit of its relative frequency in a large number
of trials. Frequentist inference is undefined, for example, when there
are no trials from which to calculate a probability. By defining
probability relative to frequencies of physical events, frequentists
attempt to objectify probability. However, de Finetti asserts that the
frequentist (or objective) interpretation always reduces to a subjective
interpretation of probability, because probability is a human
construct and does not exist independently of humans in
nature. Therefore, probability is a degree of belief, and is called
subjective or personal probability.
Value
The de.Finetti.Game function returns a vector of length
two. The respective elements are the lower and upper bounds of the
subjective probability of the participant regarding the possible event
in the near future.
