Statistical inference of multivariate time series and functional data using new dependence metrics
… we propose a nonparametric conditional mean independence test for a response variable Y given a covariate variable X, both of which can be function-valued or vector-valued. The test is built upon Functional Martingale Difference Divergence (FMDD) which fully measures the conditional mean …

Equitability and dependence
… for all non-trivial relationships using an independence test can yield too many results to be a useful approach. What is needed is a way of identifying a smaller set of "strongest" relationships, independent of relationship type (e.g., linear, exponential, etc.). The first goal of this work …

Modeling order guidelines to improve truckload utilization
… on a scatter plot analysis and a chi-square independence test. Second, we explore the impact of using linear programming to allocate SKUs to different shipment, highlighting the reduction in the number of shipments through better truck mixing. Finally, we divide the SKUs into three groups: …

System-wide Safety Analysis of a Complex Transportation Facility: Urban Freeway Off-ramps
… characteristics of each off-ramp segment. A test for independence was performed to identify if a statistically significant difference existed between type of collision and severity of crashes with respect to ramp geometry and traffic control. Significant geometric and traffic variables were …

Modeling person-to-person contaminant transport in enclosed environments
… Traditionally, modelers have conducted an independence test in order to find a reasonable value for this particle number. However, the unguided process of an independence test can be highly time-consuming. Therefore, this investigation developed a method for estimating the necessary …

Factors Contributing to the Success of First-Generation College Students at a Research University
… statistics and Pearson’s chi-square of independence test were used to analyze first-generation students. Focus groups of FGCS were conducted to understand the factors that contributed to being on-track and strategies for success. The study’s results indicated that ethnicity and changing …

Dependence testing in high dimension
… to grow. In this thesis, we propose different testing procedures for various independence/dependence related statistical testing problems in high dimension. In the first part of the thesis, we introduce sum-of-square type tests for testing mutual independence and banded dependence structure for …

Spontaninių judesių poveikis pusiausvyrai ir eisenai pacientams po galvos smegenų insulto /
… To assess the results was used: functional independence test, Barthel index, the Berg Balance scale, functional reach test, Tinetti balance and gait scale, „Up and Go“ test and Lovett grading scale of muscle strength. Statistical analysis was performed using „R Commander“ and „Microsoft …

Statistical inference for high-dimensional data
… Hilbert-Schmidt covariance (aka Hilbert-Schmidt independence criterion [Gretton et al. (2008)] and related independence tests under the high dimensional scenario. We show that the sample distance/Hilbert-Schmidt covariance between two random vectors can be approximated by the sum of squared …

Strategic behavior in risky competitive settings
… implications of mixed strategy equilibria are tested in the field using repeated observations on specific heterogeneous pairs of players, a situation that rarely repeats in real life. In this respect, I also study the effects of the usual practice of treating heterogeneous rivals as if they all …

The development of an offsite construction adoption strategic guideline for the Iraqi construction industry
… were further analysed using the Chi-Square for Independence test to determine whether there is a relationship between factors affecting the use of OSC in Iraq. Furthermore, a correlation test was conducted to identify the strength of these relationships, whilst the Kruskal-Wallis test was …
