In this paper the category, C\mathcal{C} with respect to a certain class D\mathcal{D} of subobjects of C\mathcal{C} is formed and the universality of monomorphisms of ${\overset{\lower0.5em\hbox{${\overset{\lower0.5em\hbox{ is investigated.

For generalized linear models (GLM), in case the regressors are stochastic and have different distributions, the asymptotic properties of the maximum likelihood estimate (MLE) β^n of the parameters are studied. Under reasonable conditions, we prove the weak, strong consistency and asymptotic normality of β^n  相似文献

#xa; S_n = \sum\nolimits_{i = 1}^n \xi _i ,\bar S_n = \max _{k \leqslant n} S_k . Assuming that some regularly varying functions majorize and minorize $ F = \frac{1}{n}\sum\nolimits_{i = 1}^n {F_i } $ F = \frac{1}{n}\sum\nolimits_{i = 1}^n {F_i } , we find upper and lower bounds for the probabilities P(Sn > x) and P( $ {\bar S_n } $ {\bar S_n } > x). These bounds are precise enough to yield asymptotics. We also study the asymptotics of the probability that a trajectory {Sk} crosses the remote boundary {g(k)}; i.e., the asymptotics of P(maxk$ \overset{\lower0.5em\hbox{$ \overset{\lower0.5em\hbox{ Matematicheski $ \overset{\lower0.5em\hbox{$ \overset{\lower0.5em\hbox{ Zhurnal, Vol. 46, No. 1, pp. 46–70, January–February, 2005.  相似文献

We characterize and discuss the properties of $ \mathcal{I}R $ \mathcal{I}R -closed sets and $ A_{\mathcal{I}R} $ A_{\mathcal{I}R} -sets. Also, we give characterizations of weakly $ \mathcal{I} $ \mathcal{I} -locally closed sets and $ \mathcal{I} $ \mathcal{I} -submaximal spaces. A characterization of codense ideals in terms of $ \mathcal{I}R $ \mathcal{I}R -closed sets is also given.  相似文献
