	Overcoming Bias: The Majority Is Always Wrong
		There are three major interpretations of probability: the "subjective" view of probabilities as measuring the uncertainty of agents, the "propensity" view of probabilities as chances inherent within objects, and the "frequentist" view of probabilities as the limiting value of long-run frequencies.
		I was remarking on how odd it was that frequentism, the predominant view in mainstream statistics, is the worst of the three major alternatives (in my view, you have to presume either uncertainty or propensity in order to talk about the limiting frequency of events that have not yet happened).
		At this point the light bulb went on over my head - a fluorescent light bulb - and I understood what Marcello was saying: an alternative to frequentism that was even worse than frequentism would have dropped off the radar screens long ago.

		The frequentist position is the one you probably heard at school: perform an experiment lots of times, and measure the proportion where you get a positive result - this proportion, if you perform the experiment enough times, is the probability.

	The Frozen Texan: dispositional frequentism vs. propensity theory
		According to dispositional frequentism, then, a probability is a dispositional property of an experimental OBJECT to produce a relative frequency when a GIVEN experimental-system TYPE is repeatedly instantiated on it.
		According to dispositional frequentism, the dispositional property (which, by the way, is supposed to be a real metaphysical property) accounts for the observed frequencies directly.
		To return to dispositional frequentism, the problem you point out for the frequentist who chooses to go the finite route is the same for the one who goes the infinite route: in both cases the statement "if we were...

	Probability interpretations - InformationBlast
		The word probability has been used in a variety of ways since it was first coined in relation to games of chance.
		There are 2 broad categories of probability interpretations: Frequentism assigns probabilities only to random events according to their relative frequencies of occurrence.
		While frequentism is widely accepted as a scientific tool, the use of bayesian probability often raises the philosophical debate as to whether it can contribute valid justifications of belief.

		In large part, frequentism represents an extension of the “classical” theories of Laplace and Pascal, in which probability was treated as a “ratio of favorable to equally possible cases”—the paradigmatic events here being series of coin tosses, dice rolls, and other recreations of the French aristocracy.
		While the toss referred to in the first statement can be related to a well-defined collective of, precisely, coin tosses, the deictic “next” in the second statement forecloses the possibility of relating the event to any collective whatsoever—for the simple reason that there can only ever be one next toss of the coin.
		If “to make a statement about a probability is no less factual and objective that to make a statement about the length of a stick,” certain matters of belief and doubt—such as whether the stick actually exists in the first place—must be foreclosed from the very beginning (Kyburg, p.

	Manuel's Weblog: Frequentism vs. Baysian statistics
		The frequentist position is the one you probably heard at school: perform an experiment lots of times, and measure the proportion where you get a positive result - this proportion, if you perform the experiment enough times, is the probability.
		The problem comes in those cases where we haven't performed an experiment yet, or where there's no possible way an experiment could be performed - in these cases, frequentism can't help us.
		This is in contrast to frequentism, which rejects degree-of-belief interpretations of mathematical probability, and assigns probabilities only to random events according to their relative frequencies of occurrence.

		I take it on mathematical faith that it is possible to show that an unbiased estimator will when averaged over the long run provide an estimate which is equivalent to theta.
		The argument that bias is a good thing seems to particularly rely on the truth of frequentism.
		If you are happy that in the long run your expectation of your results is meaningful and equal to theta, then unbiasedness would seem to be good.

	Interpretations of Probability
		Thus, we might identify the probability of ‘heads’ on a certain coin with the frequency of heads in a suitable sequence of tosses of the coin, divided by the total number of tosses.
		A modal element has been injected into frequentism with this invocation of a counterfactual; moreover, the counterfactual may involve a radical departure from the way things actually are, one that may even require the breaking of laws of nature.
		For instance, when we say that a coin has probability 1/2 of landing heads when tossed, we mean that we have a repeatable experimental set-up -- the tossing set-up -- that has a propensity to produce a sequence of outcomes in which the limiting relative frequency of heads is 1/2.

	Bayes Rules - Business Intelligence - CFO.com
		By contrast, frequentists, though they deal with the same probability distributions as Bayesians, make fewer prior assumptions about the distribution that applies in any particular situation.
		Frequentism is thus a more robust approach, but one that is not well suited to making decisions on the basis of limited information — which is something that people have to do all the time.
		Griffiths and Tenenbaum conducted their experiment by giving individual nuggets of information to each of the participants in their study (of which they had, in an ironically frequentist way of doing things, a total of 350), and asking them to draw a general conclusion.

	Interpretations of Probability
		The crucial difference, however, is that where the classical interpretation counted all the possible outcomes of a given experiment, finite frequentism counts actual outcomes.
		Finite frequentism has no trouble meeting the ascertainability criterion, as finite relative frequencies are in principle easily determined.
		Finite frequentism meets it all too well, while limiting relative frequentism meets it in the wrong way.

		Rather than asking oneself what is the overall probability of an event, one only needs to ask, how much support does a given case lend to a given event, and make sure that these weights be additive with respect to the union of disjoint sets.
		In the example of frequentism, for instance, the constituent measures are very simple: each case lends positive support only to the outcome that occurred in this case, and the resulting measure has single atom in this outcome.
		All the rest is done by aggregation over cases as in the theorem.
