Local, Open Economies Within the US: How Do Industries Respond to Immigration?
TL;DR: This article found that relative wages and employment rates in different local labor markets of the US are surprisingly unaffected by local factor supplies and that interregional trade mitigates the local impact of supply shocks.
Journal ArticleDOI
Clustering via nonparametric density estimation
Adelchi Azzalini,Nicola Torelli +1 more
TL;DR: Given a set of observations, a nonparametric estimate of the underlying density function is constructed, and subsets of points with high density are formed through suitable manipulation of the associated Delaunay triangulation.
Journal ArticleDOI
Maternal diet during pregnancy is related with the infant stool microbiome in a delivery mode-dependent manner
Sara N. Lundgren,Juliette C. Madan,Juliette C. Madan,Jennifer A. Emond,Hilary G. Morrison,Brock C. Christensen,Margaret R. Karagas,Anne G. Hoen +7 more
TL;DR: It is indicated that maternal diet influences the infant gut microbiome and that these effects differ by delivery mode, and linear models suggested additional associations between maternal diet and infant intestinal microbes in both delivery mode strata.

Characterisation of archaeological mortars from Pompeii (Campania, Italy) and identification of construction phases by compositional data analysis
Domenico Miriello,Donatella Barca,Andrea Bloise,Annamaria Ciarallo,Gino Mirocle Crisci,Teresa De Rose,Caterina Gattuso,Flavia Gazineo,Mauro Francesco La Russa +8 more
TL;DR: In this article, compositional characterisation of coccciopesto and natural pozzolanic mortars sampled in the Regio VI area of the archaeological site of Pompeii, with particular reference to the Casa di Pansa in Insula 6 and Casa 17 in Inula 2.
Journal ArticleDOI
CCLasso: correlation inference for compositional data through Lasso
TL;DR: A novel method called CCLasso based on least squares with [Formula: see text] penalty to infer the correlation network for latent variables of compositional data from metagenomic data is proposed and an effective alternating direction algorithm from augmented Lagrangian method is used to solve the optimization problem.

Problems of relative growth
TL;DR: This detailed study of the different rates of growth of parts of the body relative to the body as a whole represents Sir Julian Huxley's great contribution to analytical morphology, and it is still a basis for modern investigations in morphometrics and evolutionary biology.

Experiments with Mixtures: Designs, Models and the Analysis of Mixture Data
TL;DR: In this paper, the original Mixture Problem is described and models for exploring the Entire Simplex Factor Space are presented, including matrix algebra, least squares, and the analysis of variance.
New statistical methods for allometry with application to
TL;DR: In this paper, Mosimann et al. presented new statistical methods for the study of size and shape, and used these methods to study the morphology of red-winged blackbirds, Agelaius phoeniceus breeding in Florida.

Analysis of dispersion on a sphere
TL;DR: In this article, a series of approximate tests of significance is given for hypotheses about the precision constant K and the polar vector on a sphere, where 8' is the angle between the polar and observation vectors.
