Correlation exploitation in error ranking

ACM SIGSOFT Software Engineering Notes, 2004
Static program checking tools can find many serious bugs in software, but due to analysis limitations they also frequently emit false error reports. Such false positives can easily render the error checker useless by hiding real errors amidst the false.

Sampling Rank Correlated Subgroups

2019
Data mining, a key technique in knowledge discovery, is the process of identifying useful patterns from a collection of data. This process is made difficult for complex data combining, for example, numeric and symbolic attributes, or also when the number of observations is large.

A Coefficient of Correlation Based on Ratios of Ranks and Anti-ranks

Jahrbücher für Nationalökonomie und Statistik, 2013
SummaryRank association is a fundamental tool to express dependence for ordinal data. Measures of rank correlation have been developed in several contexts for more than a century and we were able to cite more than thirty of these coefficients, from simple ones to relatively complicated definitions involving one or more systems of weights. However, only

RANK TESTS OF PARTIAL CORRELATION

Bulletin of Mathematical Statistics, 1981
Rank statistics to test the null hypothesis that X and Y are conditionally, given Z, independent are given and their asymptotic properties are investigated under the model (X, Y, Z) = (U+ anW, V-FbnW,W) where (U, V) and W are independent. It is shown that linear rank tests given by (X, Y) based on the random sample of size n are asymptotically ...

Ranking the Correlates of Psychotherapy Duration

Administration and Policy in Mental Health and Mental Health Services Research, 2002
This study examined the relative strength (importance) of associations between the number of treatment sessions in mental health clinics and some pretherapy (e.g., payer source), treatment (e.g., use of medication), and outcome (e.g., improvement) variables. Data on clients who withdrew prematurely (dropouts) and data on those discharged by counselors (

On rank correlation in information retrieval evaluation

ACM SIGIR Forum, 2007
Some methods for rank correlation in evaluation are examined and their relative advantages and disadvantages are discussed. In particular, it is suggested that different test statistics should be used for providing additional information about the experiments other that the one provided by statistical significance testing. Kendall's τ is often used for
