The seismic design and assessment of steel moment resisting frames (SMRFs) rely heavily on drifts. It is unsurprising, therefore, that several simplified methods have been proposed to predict lateral deformations in SMRFs, ranging from the purely mechanics-based wholly data-driven, which aim alleviate structural engineer's burden conducting detailed nonlinear analyses either as part preliminary...

The weighted Weibull model is proposed following the method of Azzalini (1985). Basic properties of the distribution including moments, generating function, hazard rate function and estimation of parameters have been studied.

In hazard regression (HARE), the logarithm of the conditional hazard function of a survival time given a covariate is modeled by a sum of polynomial splines and their tensor products. Under appropriate conditions, it has been shown that the (nonadaptive) HARE estimate of the conditional log-hazard function possesses an optimal L 2 rate of convergence. The current paper considers the L oo rates ...

This text describes the way of estimating the hazard rate of survival data based on techniques which were introduced by Arjas, E., Gasbarra, D. (1994). The point is the assumption of piecewise constant hazard rate with varying number and size of intervals. The estimation is slighty shifted to hierarchical model and changing the dimension of the model via adding of new jumps or deleting the exis...

One of the most important asymmetrical probability distributions that recently presented as an extension conventional exponential distribution is alpha power distribution. It may be compared to various well-known models, such Weibull and gamma distributions. As a result, using adaptive progressive Type-II hybrid censoring scheme, this paper investigates estimation problems Maximum likelihood Ba...

The nonparametric estimation for the density and hazard rate functions for right-censored data using the kernel smoothing techniques is considered. The “classical” fixed symmetric kernel type estimator of these functions performs well in the interior region, but it suffers from the problem of bias in the boundary region. Here, we propose new estimators based on the gamma kernels for the density...

in this paper, the cox proportional hazard model is used to answer several questions. in general, fourteen variables are applied in four groups: firm, industry, expenditure human resources specific characteristics as well. according to the previous literature in this field, the findings of this paper also show that the factors which affect life duration of firms are different between industries...

This paper explores implications of nominal rigidity characterized by a non-constant hazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazard function and parameterize it with the Weibull duration model. The resulting Phillips curve involves lagged in‡ation and lagged expectations. It nests the Calvo NKPC as a limiting case in the sense that the e¤ects of both terms a...
