TwoSampleTest.HD: An R Package for the Two-Sample Problem with High-Dimensional Data
No full textThe two-sample problem refers to the comparison of two probability distributions via two independent samples. With high-dimensional data, such comparison is performed along a large number p of possibly correlated variables or outcomes. In genomics, for instance, the variables may represent gene expression levels for p locations, recorded for two (usually small) groups of individuals. In this paper we introduce TwoSampleTest.HD, a new R package to test for the equal distribution of the p outcomes. Specifically, TwoSampleTest.HD implements the tests recently proposed by (Cousido- Rocha, Uña-Álvarez, and Hart 2019) for the low sample size, large dimensional setting. These tests take the possible dependence among the p variables into account, and work for sample sizes as small as two. The tests are based on the distance between the empirical characteristic functions of the two samples, when averaged along the p locations. Different options to estimate the variance of the test statistic under dependence are allowed. The package TwoSampleTest.HD provides the user with individual permutation p-values too, so feature discovery is possible when the null hypothesis of equal distribution is rejected. We illustrate the usage of the package through the analysis of simulated and real data, where results provided by alternative approaches are considered for comparison purposes. In particular, benefits of the implemented tests relative to ordinary multiple comparison procedures are highlighted. Practical recommendations are given.The authors acknowledge financial support from the Grant PID2020-118101GB-I00, Ministerio de

The tunic is leathery and rough with numerous organisms encrusting the brown or light brown surface (Fig. 15). The tunic is white inside and has a yellowish soft membrane. In the field, the siphons show four small triangular lobes, the oral siphon is usually apical and the atrial more lateral. There are long spines (~160 µm) lining both siphons with a very distinctive shape: narrow with a round enlargement in the middle and at the posterior extremity (Fig. 16C, D). Iridescent spots of blue, green or yellow color caused by the reflection of light by the enlarged areas of the spines are seen against a brown or reddish background (Fig. 15). After long fixation, the tunic turns light brown. Often, a tinge of red can still be seen around the siphons. The body wall has many longitudinal muscles radiating from the siphons; they form thin bands that cross each other making a musculature net. Circular muscles densely surround both siphons. The U-shaped right gonad and the enlarged secondary loop of the alimentary canal on the left side are visible through the transparent body wall (Fig. 16A, B). The tentacles project at the level of a strong muscular sphincter, the number ranging between 16–29. They are flat, very wide at the base and ramifying two or three times, with primary ramifications projecting along the posterior margin (Fig. 16E, F). The third order ramifications are minute and only appear in the largest tentacles that can reach 7 mm in length. The peritubercle region forms a deep V with the dorsal tubercle has U- or C-shaped aperture with enrolled ends. The dorsal lamina is divided in numerous thin and long densely packed languets. The pharynx has six folds per side and is orange when fresh (Fig. 16G), but quickly loses coloration after fixation. The number of longitudinal vessels range from 305 to 410. Longitudinal vessels fray toward the base of the animal, making languets around the esophageal opening. Parastigmatic vessels are present. Endocarps are present along the intestine, especially along the descending limb (Fig. 17B). Both gonads have large endocarps on each lobe, particularly the distal ones (Fig. 17C).

Ventral right gonad. 1 character variation includes information in Monniot (1994), 2 character variation includes information in Monniot (1983) and Monniot (2018); 3 character variation includes information in Tokioka (1972) The alimentary canal occupies 2/3 of the left side. The primary loop does not reach the peripharyngeal groove, forms a close curve with a vertical descending limb that forms another close second loop with the ascending rectum (Fig. 17A). The intestine is not isodiametric; the secondary loop and rectum are enlarged. The anus is lobed. The digestive gland is dark green and forms lobes connected by long tubes as in a cauliflower. It has two main connections to the stomach. On the left side, the gonad completely fill the space within the primary intestinal loop, the number of gonad lobes ranging from 30–47. The right side of the animal is occupied by a large characteristic Ushaped gonad with 26 to 42 gonadal lobes. The gonoducts are long, the oviduct slightly longer than the sperm duct, both opening at the level of the anus. Remarks. This is one of the most common species both in mangrove and reefs around Bocas del Toro province (Rocha et al. 2005) and also found in Colon region but it has not been found on a survey of the Pacific coast (Carman et al. 2011). The specimens from Panama agree well with the description of P. vittata from Guadeloupe and Martinique (Monniot, C. 1983; Monniot, F. 2018). We believe that P. vittata reported by F. Monniot (2016) from French Guiana is actually P. beta Skinner, Rocha & Counts, 2019.Published as part of Rocha, Rosana M. & Counts, Bailey Keegan, 2019, Pyura (Tunicata: Ascidiacea: Pyuridae) on the coasts of Panama, pp. 491-513 in Zootaxa 4564 (2) on pages 509-512, DOI: 10.11646/zootaxa.4564.2.9, http://zenodo.org/record/258940

Small size (2.2 mm). Antenna dark brown (Fig. 6A). Scutum distinctly pyramidal-shaped, broader than mesopleuron in lateral view (Figs 6A, B), covered with reddish brown pruinescence, paler on prescutellar disc. Wing hyaline; pterostigma divided into two small quadrangular spots, one posterior to apex of vein R 1, and one filling apex of cell r 1; R 2+3 strongly angulate apically; second section of M 1 about 1/4 length of crossvein r-m; cells bm and cua subequally long, both longer than cell br (Fig. 6E).

Syneches angulatus was previously registered only from the Amazon biome and is now known to occur also in the Cerrado biome. Remarks. Syneches angulatus differs from all other Brazilian species with the scutum broader than the mesopleuron by having R 2+3 strongly angulate apically and the second section of vein M 1 noticeably short, about 1/4 length of crossvein r-m. This species apparently forms a monophyletic group with S. annulipes Bezzi, S. bilobatus Menezes & Ale-Rocha, S. maculosum Menezes & Ale-Rocha, S. pyramidatus Bezzi and S. vidali Ale-Rocha & Vieira, sharing a small size (2–3 mm), scutum broader than mesopleuron in lateral view and usually pyramidal-shaped, femora brown to black, but fore and mid femora with yellow apex, and male terminalia remarkable similar, with simple short phallus and hypandrium lacking projections or deep concavities.Published as part of Soares, Matheus M.
