JOHANSEN TEST FOR COINTEGRATING TIME SERIES ANALYSIS IN R The rank of the matrix A is given by r and the Johansen test sequentially tests whether this rank r is equal to zero, equal to one, through to r = n − 1, where n is the number of time series under test. The null hypothesis of r = 0 means that there is no cointegration at all. COINTEGRATED AUGMENTED DICKEY FULLER TEST FOR PAIRSSEE MORE ON### QUANTSTART.COM

MONTE CARLO SIMULATIONS IN CUDA BASICS OF STATISTICAL MEAN REVERSION TESTING y ( t) = β x ( t) + ϵ ( t) Where y ( t) is the price of AREX stock and x ( t) is the price of WLL stock, both on day t. If we plot the residuals ϵ ( t) = y ( t) − β x ( t) (for a particular value of β that we will determine below) we create a new time series that, at first glance, looks relatively stationary. This is given in Figure 3: THE MARKOV AND MARTINGALE PROPERTIES The Markov and Martingale Properties | QuantStart. In order to formally define the concept of Brownian motion and utilise it as a basis for an asset price model, it is necessary to define the Markov and Martingale properties.

QSTRADER - QUANTSTART QSTrader is an open source backtesting simulation framework written in Python. It is primarily intended for long/short systematic trading strategies utilising cash equities and ETFs. It is highly modular, object-oriented and freely available. QSTrader is currently used by the QuantStart.com team for internal quant strategy research, by the SERIAL CORRELATION IN TIME SERIES ANALYSIS The serial correlation or autocorrelation of lag k, ρ k, of a second order stationary time series is given by the autocovariance of the series normalised by the product of the spread. That is, ρ k = C k σ 2. Note that ρ 0 = C 0 σ 2 = E σ 2 = σ 2 σ 2 =### 1.

THE BIAS-VARIANCE TRADEOFF IN STATISTICAL MACHINE LEARNING The bias-variance tradeoff is a particular property of all (supervised) machine learning models, that enforces a tradeoff between how "flexible" the model is and how well it performs on unseen data. The latter is known as a models generalisation performance. We will begin by understanding why model selection is important and then### discuss the

WHY A MASTERS IN FINANCE WON'T MAKE YOU A QUANT TRADER A quantitative hedge fund makes money through a common hedge fund structure known as "2 and 20". This basically means that if 100million is invested with the fund then each year the fund receives a 2% management fee (the "2") and then a 20% performance fee (the "20") of the money under management.
