Webno auto-correlation (we’ll return to this topic in the next chapters) Auto-correlation or serial correlation is an important characteristic of time series data and can be defined as the correlation of a variable with itself at different time points. Autocorrelation has many consequences. It prevents us to use traditional statistical methods ... Web21 Jul 2024 · A test statistic of 2 indicates no serial correlation. The closer the test statistics is to 0, the more evidence of positive serial correlation. The closer the test statistics is to 4, the more evidence of negative serial correlation. As a rule of thumb, test statistic values between the range of 1.5 and 2.5 are considered normal.
Web5 Apr 2024 · Whereas for the In-sample period, the Q-statistic and corresponding p-values are all greater than 0.05, hence implying no serial correlation. There is a contradiction.

The left panel of figure 5 represents a highly liquid asset for which the largest realised volatility estimates occur at the highest sampling rates, corresponding to the smallest values of k. This can be explained by negative serial correlation in the returns, most likely induced by bid-ask bounce.

In particular, we show that the realized variance measure is a biased esti-mator of the conditional return variance when returns are serially correlated. … WebAcquisition, and Serial Correlation* I. Introduction Jegadeesh and Titman (1993) find that momentum strategies, which buy stocks that have performed well in the past and vice versa, generate significant ab-normal returns over a medium-term holding period of 3 to 12 months.

Web9 Mar 2024 · Autocorrelation, also known as serial correlation, refers to the degree of correlation of the same variables between two successive time intervals. The value of autocorrelation ranges from -1 to 1. A value between -1 and 0 represents negative autocorrelation. A value between 0 and 1 represents positive autocorrelation.
Web7 Jan 2016 · As for the correlation of returns and absolute returns over time, the serial correlation of returns is usually analyzed by computing the autocorrelation function (ACF).
