Inference for Partially Identified Econometrics
... for θ ∈ Θ. The point of departure from the classical extremum estimation framework is that it is not assumed that Q(θ, P ) has a unique minimizer in the parameter space Θ. The goal may be either to draw inferences about some unknown point in the set of minimizers of the population objective function ...

... 2. The roulette wheel at a casino has integers from 1 to 36, together with 0. Half of the non-zero numbers are red, the other half are black, and 0 is green. Any of the numbers between 0 and 36 is equally likely to occur each time the wheel is spun. Fred has £100 to gamble on roulette at the casino ...

Law of large numbers
In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed.The LLN is important because it ""guarantees"" stable long-term results for the averages of some random events. For example, while a casino may lose money in a single spin of the roulette wheel, its earnings will tend towards a predictable percentage over a large number of spins. Any winning streak by a player will eventually be overcome by the parameters of the game. It is important to remember that the LLN only applies (as the name indicates) when a large number of observations are considered. There is no principle that a small number of observations will coincide with the expected value or that a streak of one value will immediately be ""balanced"" by the others (see the gambler's fallacy)
