Laoban, 29°58'32.8"N, 102°59'46.4"E, elev. 587m, 22 October 2014, Y.J. Lin leg. Paratypes: 3 males and 3 females, with same data as holotype (SWUC); CHINA: Chongqing: 6 females, Jinyun Mountain National Nature Reserve, 29°50′12″N, 106°23′45″E, elev. 749m, 0 9 June 2014, X.W. Meng & J. Yang leg. (SWUC). Etymology. The specific name comes from a Latin word “ serratus ” meaning serrated, referring to the shape of apex of the embolic basal process; adjective. Diagnosis. The new species is similar to P. bowo (Zhu et al., 2006) in having a wider RTA and an expanded embolic base. However, it can be distinguished by the relatively short and wide RTA, the serrated apophysis of the embolic base and the straightly protruding median apophysis (Figs 1 G, 2B–E) of the male pedipalp, and the length of copulatory ducts about 1/3 of the female epigyne. Description. Male holotype (Figs 1 A, E–G, 2C–F) total length 6.58. Prosoma 2.72 long, 4.06 wide; opisthosoma 3.81 long, 3.93 wide. Carapace yellow brown, semicircle, sparsely set with brown hairs, margin evenly with spines. Anterior eye row slightly recurved, posterior eye row recurved.

Chelicerae with three promarginal, three retromarginal teeth. Endites, clypeus pale yellow, longer than wide. Sternum pale yellow, sparsely set with brown hairs. Legs yellow brown, metatarsi, tarsi darker. When alive, legs I–II, femora III–IV red brown, rest dark brown. I 10.23 (3.54, 3.67, 1.91, 1.11); II 14.77 (4.88, 5.40, 3.14, 1.35); III 13.97 (4.71, 5.00, 2.98, 1.28); IV 11.64 (3.86, 3.84, 2.81, 1.13); Leg formula: 2341. Opisthosoma almost circular, widest at middle. Dorsum yellow brown, dorsal surface with vast dark brown hairs. Venter yellow brown, edges darker. Male palp (Figs 1 E–G, 2C–E). RTA longer than wide. Embolic base with many serrated processes. Conductor membraneous, originating between embolic base and median apophysis. Median apophysis developed, straight with sharp apex in ventral view. Embolus thin, short. One female paratype (collected from Mt. Laoban, Figs 1 B–D, 2A–B) total length 9.57. Prosoma 3.22 long, 5.19 wide; opisthosoma 6.10 long, 5.53 wide. Eye sizes and interdistances: AME 0.14, ALE 0.15, PME 0.15, PLE 0.17; AME–AME 0.15, AME–ALE 0.15, PME–PME 0.34, PME–PLE 0.43, ALE–PLE 0.29. MOA 0.42 long, front width 0.51, back width 0.62. Clypeus height 0.11. Appearance of opisthosoma and legs as male. Leg measurements: I 11.35 (4.09, 4.1, 1.91, 1.25); II 17.07 (5.87, 6.4, 3.34, 1.46); III 16.9 (5.92, 6.15, 3.42, 1.41); IV 13.44 (4.78, 4.56, 2.96, 1.14). Leg formula: 2341. Epigyne (Figs 1 C–D, 2A–B) butterfly-like. Copulatory ducts short, thick, V-shaped. Two pairs of receptacle located behind copulatory ducts. One larger pair, close to copulatory openings, termed subspermathecae according Zhang & Zhang (2013) in Hahniidae. Smaller pair, termed spermathecae, connected with fertilization ducts. Distribution. China (Sichuan, Chongqing) (Fig. 4). Remark. Individuals of the new species were collected under the bark of Platanus orientalis in Mt. Laoban of Sichuan, while under tiles around the house of residents in Mt. Jinyun of Chongqing.Published as part of Lin, Ye-Jie & Zhu, Guang-Xiang, 2016, A new species of the spider genus Plator (Trochanteriidae) from south China, pp. 189-192 in Zootaxa 4162 (1) on pages 189-192, DOI: 10.11646/zootaxa.4162.1.11, http://zenodo.org/record/26764

Computation of a test statistic in data quality control
No full textWhen processing observational data, statistical testing is an essential instrument for rendering harmless incidental anomalies and disturbances in the measurements. A commonly used test statistic based on the general linear model is the generalized likelihood ratio test statistic. The standard formula given in the literature for this test statistic is not defined if the noise covariance matrix is singular, and is not suitable for computation if any of the matrices involved are ill-conditioned. Based on Paige’s generalized linear least squares method [Comm. Statist. B—Simulation Comput., 7 (1978), pp. 437–453], a numerically stable approach is proposed for the computation of the test statistic, as well as for the estimates of the parameter vectors, and reliable representations of the error covariance matrices for these estimates are presented. This approach allows the noise covariance matrix to be singular and can be applied directly to the linear model with linear equality constraints.Remote SensingAerospace Engineerin
