Some general aspects of the log-logistic distribution (LLD) are discussed in Chapter 17. The three-parameter log-logistic distribution (LLD3) is a generalization of the two-parameter log-logistic distribution.
Binary logistic regression versus stochastic gradient boosted decision trees in assessing landslide susceptibility for multiple-occurring landslide events: application to the 2009 storm event in Messina (Sicily, southern Italy). Nat. Hazards 79(3), 1621-1648, https://doi.org/ 10.1007/s11069-015-...
Let Y={1,−1}, x=〈1,2,−3,1〉 with d(x)={−1,1} and consider a linear classifier A with initial parameter configuration w=〈1,1,1,1〉 and loss function L=max{0,1−y(w⋅x)}. Then Lint(A(x),{−1,1})=[0,2] and, the new parameter vector becomes wmin=〈...
Data was analyzed with Prism v9.4.1 using 4-parameter logistic curve fit. Competition ELISAs RBD and P.1 Spike competition ELISAs were performed as above with some modifications. For the P.1 competition ELISA, the plates were coated using BV2373 protein (WA-1 Spike, Novavax). Serially ...
The IC50 value was determined by the 4-parameter logistic (4PL) regression using GraphPad Prism (version 8.0.1) (https://www.graphpad.com). Pseudovirus neutralization assay based on VSV pseudovirus Omicron variant and D614G pseudovirus using Vesicular Stomatitis Virus (VSV) carrying the spike ...
(see Ben-Akiva and Lerman1985, page 70.) The difference between the two is that logit relies on the logistic distribution—differentiated from the normal by its thicker tails, or greater kurtosis (Forbes et al.2011). Logit parameters are about 1.6 times as large as probit parameters so ...
We obtain one parameter estimate for each variable. These estimates are listed in the equation subtable labeled restaurant. For the second equation, we specify the type variable. It identifies the first-level alternatives, the restaurant types. Following the colon after type, we specify two case-...
Figure 3d,e shows a one-parameter model (black line) that estimates the size of the average localization shift as a proportion of the perturbation using all trials (colored lines). Even though the model over-estimates the size of change in hand localizations during the reversal period, it ...
To compare the performance of the conservative equal costs mechanism and our DP solution, we focus on distributions that are not log-concave (hence, uniform and normal are not eligible). We introduce the following non-log-concave distribution family: ...
We then used the parameter estimates to describe the reproductive characteristics of fish observed in Suva fish markets. The absence of females in the largest size classes of all three species suggests that, at the population level, individuals well below maximum size are responsible for the ...
