Averaging and oversampling correlator receiver with input quantization
Digital Signal Processing, 2006Correlation is a fundamental technique to detect signals buried in noise. However, due to noise, the fluctuations of the output signal may be significant and the detection of the desired signal can then fail. It is known that a simple one-bit correlator receiver can give nearly identical performance to the full precision correlator in determining time ...

The Journal of Finance, 1989
ABSTRACTThis paper presents a portfolio approach to estimating the average correlation coefficient of a group of stocks which are considered for portfolio analysis. The average correlation coefficient has been shown to produce a better estimate of the future correlation matrix than individual pairwise correlations.

Correlated High Average-Utility Itemset Mining
2020High average-utility itemset (HAUI) mining is an advancement over high utility itemset mining, where average-utility is used instead of utility measure to discover meaningful patterns. It has been discussed in several past studies that significance of utility-based patterns can be amplified if items in the patterns are correlated.

More Voodoo Correlations: When Average-Based Measures Inflate Correlations
The Journal of General Psychology, 2012A Monte-Carlo simulation was conducted to assess the extent that a correlation estimate can be inflated when an average-based measure is used in a commonly employed correlational design. The results from the simulation reveal that the inflation of the correlation estimate can be substantial, up to 76%.

Dangers Inherent in Correlating Averages
The Journal of Educational Research, 1962OVER A PERIOD of years many studies in edu cation and psychology have been conducted in which statistical techniques involving the correlation of averages have been employed. Few basic statistical texts have devoted sufficient coverage to the dangers inherent in the use of this technique.
