Table 4: Comparison of hierarchical models (linear and nonlinear) with non-hierarchical models (linear and nonlinear) based on protein fold classiflcation data.

by Babak Shahbaba, Radford M. Neal 2007
"... In PAGE 12: ... We refer to this models as dpCorMNL. Table4 presents the results for the two linear models (with and without hierarchy-base priors), and two nonlinear models (with and without hierarchy-based priors). In this table, \parent accu- racy quot; refers to the accuracy of models based on the four major structural classes, namely fi, fl, fi=fl.... ..."

in Linearity Testing using Local Polynomial Approximation
by Vidar Hjellvik, Qiwei Yao 1998
"... In PAGE 16: ... Much of the emphasis will be on the choice of bandwidth and the new aspects brought in by using local polynomial approximation. A power experiment on a wide class of nonlinear models listed in Table2 has been conducted in Section 6.3.... In PAGE 18: ...Table2 , however, where M1(x) is approximately quadratic (see Figure 1), as can be expected the best result is achieved with T = 2 and h = 1. For the ^ L(V1)-tests the size tends to be too low.... In PAGE 18: ... If no corrections are made for this e ect, it will lead to conservative tests. Figure 5 shows the power of the ^ L(V )-tests for model la) of Table2 , and we see the same general trend as for the ^ L(M)-tests; the optimal h increases with T and the derivative. Here ^ L1(V1) also has some power for h = 1 because the variance is constant, not only linear, under the null hypothesis.... In PAGE 18: ... Here ^ L1(V1) also has some power for h = 1 because the variance is constant, not only linear, under the null hypothesis. ^ L0(V1) is much more robust than ^ L0(M1), and this is the case for the other models listed in Table2 as well. 6.... In PAGE 18: ... In particular when we have a nonlinear model, we do of course not want h = 1 to be chosen when T = 0 or T = 1, but with a small autocorrelation, this may well happen for T = 0. In fact h = 1 was chosen in 136 of 500 realizations of model lc) of Table2 which is clearly nonlinear (cf. Figure 1)....

Table 3: Number of accepted and rejected candidates in the presence of negative curvature 5 Conclusion We have exploited powerful and up-to-date technics in non-linear programming and adapted them to the problem of simultaneous estimation of hierarchical logit models. An optimiza- tion algorithm that is based on a quasi-Newton technic combined with trust region strat- egy, ensuring robustness and global convergence, and a modi ed preconditioned conjugate gradients iterations, exploiting non-concavity. The method has been applied to two numerical examples derived from real exercices, illustrating its major features, and clarifying the e ect of some algorithmic options. The algorithm described in this paper has been included in the HieLoW package (Bierlaire, 1994 and Bierlaire and Vandevyvere, 1995).

in A Robust Algorithm For The Simultaneous Estimation Of Hierarchical Logit Models
by M. Bierlaire
"... In PAGE 17: ... This rejection, followed by a reduction of the trust region size, insures the robustness of the algorithm when the model doesn apos;t t correctly the objective function or when singularity in the quadratic model is detected. If the number of rejections seems larger, especially when approximated Hessian is used (see column NO of Table3 , the number of instances where non-convexity is exploited is...

"... In PAGE 9: ... In order to have easy interpretable models, we have fixed the maximal number of terms in the equation to be equal to 8 and the maximum degree of polynoms to be equal to 3. The calculations performed using the select params option of the ANALYSIS are summarized in Table1 . The number of stored models was 3.... In PAGE 9: ... It was shown that the use of significant variables, as detected by MUSEUM, = improved PLS results (compare data in column 7 vs. column 6 in Table1 ). The similar tendency was also observed if only variables found to be relevant by the PNN algorithm were used in the cross-validation calculations (compare the last and 7 columns of Table 1)....

Table 2. Distribution of number of individuals within households No. of individuals

in THE INFLUENCE OF HOUSEHOLDS ON DRINKING BEHAVIOUR: A MULTILEVEL ANALYSIS
by Nigel Rice, Roy Carr-hill, Paul Dixon, Matthew Sutton
"... In PAGE 4: ... Although it does not make sense to attempt to esti- mate components of variation attributable to indi- viduals and households using data from one-person households (as the two eC128ects cannot be disen- tangled), one-person households were retained in the analysis as they contribute to the estimates of the covariates of alcohol consumption and to area variations in consumption. The distribution of num- bers of individuals within households is given in Table2 . The vast majority of the sample live in two-person households.... ..."

"... In PAGE 9: ... We thus obtain eight different methods that correspond to all possible combinations of three concepts above: the first one is the linear preprocessing (PCA or PLS), the second one is the optional whitening and the last part is the nonlinear model (RBFN or LS-SVM). Methods are sum- marized in Table1 (see also Fig. 4).... ..."
