CONTEXT The Functional Movement Screen (FMS) is an assessment tool for quality of human movement. Research reports a significant difference between FMS scores of subjects who later experienced injury and those who remain uninjured. OBJECTIVE To systematically review literature related to predictive validity of the FMS. From the aggregated data, a meta-analysis was conducted to determine the p...

We introduce a simple, interpretable strategy for making predictions on test data when the features of the test data are available at the time of model fitting. Our proposal—customized training— clusters the data to find training points close to each test point and then fits an l1-regularized model (lasso) separately in each training cluster. This approach combines the local adaptivity of k-nea...

This paper investigates a SRGM (software reliability growth model) based on the NHPP (nonhomogeneous Poisson process) which incorporates a logistic testing-effort function. SRGM proposed in the literature consider the amount of testing-effort spent on software testing which can be depicted as an exponential curve, a Rayleigh curve, or a Weibull curve. However, it might not be appropriate to rep...

Presented in the paper is an efficient pair-wise offset algorithm for closed 2D point-sequence curves (PS-curve). A key feature of the proposed algorithm is that all local invalid loops are removed from the input PS-curve before constructing a raw offset-curve, by invoking a pair-wise interference-detection (PWID) test. In the PWID test, each pair of elementary offset segments is tested for int...

The ScoliScoreTM AIS (adolescent idiopathic scoliosis) prognostic DNA-based test (Axial Biotech, Salt Lake City, UT) is a saliva-based genetic test designed to predict the risk of progression of scoliosis in patients with AIS. The test uses an algorithm incorporating results of testing for 53 single nucleotide polymorphisms (SNPs), along with the patient’s presenting spinal curve (Cobb angle) t...

The t-test is as defined in the previous lecture. It has slope 1/σ. The Mann-Whitney test rejects if 1 nm ∑ i,j I(Xi ≤ Yj) is large. Note. The Mann-Whitney statistic has a relationship with the area under the ROC curve (AUC) for classification algorithms with a tunable parameter. The ROC plot has one axis for proportion of false positives and one axis for proportion of true positives; as we mov...

On August 2002, Agrawal, Kayal and Saxena announced the first deterministic and polynomial time primality testing algorithm. For an input n, the AKS algorithm runs in heuristic time Õ(log n). Verification takes roughly the same amount of time. On the other hand, the Elliptic Curve Primality Proving algorithm (ECPP) runs in random heuristic time Õ(log n) ( Õ(log n) if the fast multiplication is ...

Binary test outcomes typically result from dichotomizing a continuous test variable, observable or latent. The effect of the threshold for test positivity on test sensitivity and specificity has been studied extensively in receiver operating characteristic (ROC) analysis. However, considerably less attention has been given to the study of the effect of the positivity threshold on the predictive...
