A Multivariate Two-Sample Test using the Jaccard Distance
A common need in statistics is to assess whether two samples come from the same underlying population distribution. Existing two-sample tests often make limiting a priori assumptions, or cannot be easily generalized to multivariate data. We derive a new multivariate two-sample test that makes no a priori assumptions, has higher statistical power than previous tests, has better runtime performan...

متن کاملA new graph-based two-sample test for multivariate and object data
Two-sample tests for multivariate data and especially for non-Euclidean data are not well explored. This paper presents a novel test statistic based on a similarity graph constructed on the pooled observations from the two samples. It can be applied to multivariate data and non-Euclidean data as long as a dissimilarity measure on the sample space can be defined, which can usually be provided by...
متن کاملA multivariate two-sample mean test for small sample size and missing data.
We develop a new statistic for testing the equality of two multivariate mean vectors. A scaled chi-squared distribution is proposed as an approximating null distribution. Because the test statistic is based on componentwise statistics, it has the advantage over Hotelling's T2 test of being applicable to the case where the dimension of an observation exceeds the number of observations. An appeal...
متن کاملA Multivariate Two-Sample Test Based on the Concept of Minimum Energy
We introduce a new statistical quantity the energy to test whether two samples originate from the same distributions. The energy is a simple logarithmic function of the distances of the observations in the variate space. The distribution of the test statistic is determined by a resampling method. The power of the energy test in one dimension was studied for a variety of different test samples a...
