Can the Gold Coin Futures Prices Forecast the Gold Coin Spot Prices at the Maturity Date?

This paper examines whether the gold coin futures prices in the Iran Mercantile Exchange can forecast accurately the gold coin spot prices at the maturity date. For this, it uses daily data of both futures and spot prices from Azar 1387 to Tir 1397. A cointegration analysis shows that in horizons shorter than 100 days, there is a significant one-to-one relation between these two prices which im...

Parameter-Free Convex Learning through Coin Betting

We present a new parameter-free algorithm for online linear optimization over any Hilbert space. It is theoretically optimal, with regret guarantees as good as with the best possible learning rate. The algorithm is simple and easy to implement. The analysis is given via the adversarial coin-betting game, Kelly betting and the Krichevsky-Trofimov estimator. Applications to obtain parameter-free ...

Coin tosses

We’ll use a statistical model of the problem to motivate a prediction strategy, as well as to evaluate the quality of various strategies. In this model, the outcome of the coin toss is random; it is “heads” with some probability, say, p; and it is “tails” with the remaining probability 1 − p. We’ll encode “heads” by 1, and “tails” by 0, so the outcome is a random variable Y . The number p is a ...

In this model, the outcome of the coin toss is random; it is “heads” with some probability, say, p; and it is “tails” with the remaining probability 1− p. This number p is a parameter of the model; the possible values it can taken on, namely the interval [0, ...
