A note on the Bickel-Rosenblatt test in autoregressive time series
No full textIn a recent paper Lee and Na (2001) introduced a test for a parametric form of the distribution of the innovations in autoregressive models, which is based on the integrated squared error of the nonparametric density estimate from the residuals and a smoothed version of the parametric fit of the density. They derived the asymptotic distribution under the null-hypothesis, which is the same as for the classical Bickel-Rosenblatt (1973) test for the distribution of i.i.d. observations. In this note we first extend the results of Bickel and Rosenblatt to the case of fixed alternatives, for which asymptotic normality is still true but with a different rate of convergence. As a by-product we also provide an alternative proof of the Bickel and Rosenblatt result under substantially weaker assumptions on the kernel density estimate. As a further application we derive the asymptotic behaviour of Lee and Nas statistic in autoregressive models under fixed alternatives. The results can be used for the calculation of the probability of the type II error of the Bickel-Rosenblatt test for the parametric form of the error distribution and for testing interval hypotheses in this context. --Autoregressive process,goodness-of-fit test,nonparametric density estimation,asymptotic distribution under fixed alternatives

Head: Face and clypeus dark metallic blueviolet with little grey pruinosity; frons dark metallic green with dense grey pruinosity; palpus and proboscis dark brown; scape and pedicel yellow, first flagellomere black; lower postoculars white. Thorax: Dorsum dark metallic bronze-green with dusting of grayish-brown pruinosity; all thoracic setae black; 5 strong dc, and some hair-like anterior setae; ac strong and long, posteriormost ac as long as anteriormost dc; 2 strong scutellars and 2 lateral setae two-thirds length of medians; pleura dark metallic bronze-green, proepisternum with 2 strong setae below. Legs: Entirely black, tip of femora pale; all setae black, except as noted. Fore leg: bare of major setae; relative podomere ratios: 49 / 50 / 28 / 10 / 17 / 8 / 5. Mid leg: coxa with 3 strong anterolateral setae; femur with av row of setae, length nearly subequal to diameter of femur; tibia with strong ad/pd setal pair at 1 / 4, and 1 apicoventral seta; relative podomere ratios: 56 / 60 / 42 / 19 / 16 / 8 / 5. Hind leg: coxa with strong lateral seta; femur with anterior and av row of strong setae; tibia lacking major setae, with black pv apical tooth-like projection (MSSC); basitarsus with small basal tubercle opposite of tibial tooth (MSSC); relative podomere ratios: 64 / 87 / 19 / 42 / 23 / 14 / 9. Wing: Membrane slightly darkened; veins black; R 4 + 5 slightly arching posteriad distally, R 4 + 5 and M converging and becoming subparallel before wing margin; CuAx ratio: 0.6; RMx ratio: 4.8; lower calypter yellowish-brown with fan of yellowish setae; halter yellowish with dark brown stem. Abdomen: Dark metallic green; setae black Male genitalia (Figs. 4 A, B): hypandrium with rounded apex, with narrow lobe on either side; epandrial seta absent; epandrial lobes well separated each bearing strong curved seta; surstylus trifurcate, dorsal lobe narrow and acute, with apical and subapical seta, ventral lobe rounded, with blade-like subapical and 3 normal setae; cercus elongate, with strong, hornlike apical projection and 2 blade-like and 1 normal setae ventrally; aedeagus with dorsal bifurcate process projecting laterad of cercus (= “bottle-brush-like” aedeagal projection sensu Bickel (1985)). Female: Similar to male, but tibiae yellowish-brown, wings less darkened. Etymology. The species is named after the type locality. Remarks. Medtera nuwarensis probably represents a new species-group. It is similar to M. kinabaluensis Bickel, 1987 from Malaysia, the single species of the signaticornis-pinicola species-group in the Oriental Region. Both species can be separated by the characters given below. The species bears a long, narrow, apically bifurcate dorsal projection, the “bottle-brush-like” aedeagal projection according to Bickel (1985, 1987), but in M. nuwarensis the apex of this projection is not hairy as in other species of this group. Moreover, M. nuwarensis has a narrow lobe on either side of the hypandrium, a unique character within the Oriental species. 1 Body length more than 3 mm; lower calypter with pale setae; cercus distally bulbous; hypandrium with pointed apex, without lateral lobes; aedeagus without dorsal process projecting near base of cercus (see Bickel 1987, figs. 19 a, b)................................................................................................... kinabaluensis Bickel - Body length less than 3 mm; lower calypter with dark setae; cercus distally tapering; hypandrium with rounded apex, with lateral lobes on either side; aedeagus with long, narrow, bifurcate dorsal process projecting near base of cercus (Figs. 4 A, B)....................................................................................... nuwarensis sp. nov.Published as part of Naglis, Stefan & Bickel, Daniel J., 2012, Medetera (Diptera, Dolichopodidae) of Sri Lanka, pp. 55-63 in Zootaxa 3188 on pages 59-60, DOI: 10.5281/zenodo.21056

Wing: Veins brown; R 4 + 5 and M distinctly converging towards wing margin; CuAx ratio: 0.4; RMx ratio: 2.8; lower calypter pale yellow, with fan of yellow setae; haltere yellow. Abdomen: Dark metallic olive-green; setae white; epandrium black, cercus brown. Male genitalia (Fig. 5): epandrium subovate; hypandrium with acute apex; epandrial seta small, positioned near epandrial lobes; epandrial lobes very close, lateral lobe bearing long, sinuous seta, median lobe with normal seta; surstylus sickle-shaped, with basoventral, short tooth-like seta and 3 long midventral setae, apex with 4-5 short setae; cercus short, with short lateral arm. Female: Unknown. Etymology. The species is named after the type locality. Remarks. Medetera colombensis belongs to the flaviscutellum species-group which includes a single Oriental species, M. philippinensis Bickel. Using Bickel’s (1987) key, the species runs to the Australian species M. gingra Bickel and M. bunyensis Bickel which do not have a yellow colored scutellum. It can be separated from all members of this species-group by the striking sickle-shaped surstylus and small cercus.Published as part of Naglis, Stefan & Bickel, Daniel J., 2012, Medetera (Diptera, Dolichopodidae) of Sri Lanka, pp. 55-63 in Zootaxa 3188 on pages 60-61, DOI: 10.5281/zenodo.21056
Alexander M. Bickel, Political Philosopher
No full textIt is hardly surprising that with his book The Morality of Consent Alexander M. Bickel moved from constitutional scholarship into explicit political philosophy. That would seem a natural, indeed almost an inevitable, progression for scholars of the Constitution. The wonder is less that Bickel developed in that way than that so many academic scholars of the Constitution do not. There is, of course, political feeling implicit in much constitutional writing, but too often it is disguised as legal analysis; it colors and distorts constitutional judgment rather than informing it

No full textGenus Gujaratmyia Bickel gen. nov. Etymology. Gujaratmyia is the combination of the name of Indian state of Gujarat where Cambay amber occurs and the suffix - myia, Greek for “fly”. The gender is feminine. Type species. Gujaratmyia rotunda Bickel sp. nov. Diagnosis. [This generic diagnosis is based on a single male specimen and emphasizes characters considered to be of generic importance.] Body length about 1.1 mm; head large with respect to size of thorax, and ovate, higher than wide; face as narrow band separating eyes; postpedicel rounded, subtriangular, arista dorsal; posterior mesonotum apparently flattened; femora II and III each with distinct anterior preapical seta near 4/5; TII with strong ad seta at 1/3; veins R 4+5 diverging from M 1 near base, and becoming slightly bowed and subparallel with M 1 beyond level of dm-m crossvein; R 4+5 joins costa at 7/8, M 1 joins margin slightly behind wing apex; hypopygium forming ovoid cap over apex of abdomen, and with short distal appendages. Remarks. Gujaratmyia is a monotypic genus, and the species G. rotunda has the posterior mesonotum apparently flattened, the dorsal postcranium is strongly concave, femora II and III have anterior preapical setae, and the slightly divergent veins R 4+5 and M 1, all characters reminiscent of the subfamily Enliniinae, discussed above.Published as part of BICKEL, DANIEL J., MARTIN, JOHN, AGNIHOTRI, PRIYA & SINGH, HUKAM, 2022, Dolichopodidae (Diptera) from the Eocene amber deposits of Cambay and Kutch Basins, India, pp. 475-486 in Palaeoentomology 5 (5) on page 482, DOI: 10.11646/palaeoentomology.5.5.9, http://zenodo.org/record/733377
