Discrete‐time survival trees

Canadian Journal of Statistics, 2009
AbstractTree‐based methods are frequently used in studies with censored survival time. Their structure and ease of interpretability make them useful to identify prognostic factors and to predict conditional survival probabilities given an individual's covariates.

Discrete-Time Ordering Policies

IEEE Transactions on Reliability, 1979
Optimum ordering policies are discussed for units with discrete failure-time distributions. The results can include a negative ordering time. Under certain conditions, there exists a finite and unique optimum policy minimizing the s-expected cost rate.

Discrete-time Networks

1989
To realize a discrete-time filter with either computer software, a programmable DSP chip, or custom VLSI, a network must be specified describing the computations to be performed. For software realizations, the network corresponds to a flowchart of the filter algorithm, while for hardware realizations, the network describes the actual circuit elements ...

Discrete-Time Martingales

1996
A martingale is a particular sequence of dependent random variables. The concept comes from gambling systems but is also of great interest in Probability and Statistics.

Discrete-Time Entropy

1997
In Chapter 1 it was shown that controllers which minimize the entropy of the closed-loop system provide a simple means of trading off the robustness and performance that is usually associated with the H∞ and H2 cost functions for linear time-invariant systems.

Continuous and Discrete Time Models

1987
Most economists recognize that the use of discrete time is only an approximation, but assume (usually implicitly) that the error of approximation involved is trivially small relative to the other sorts of simplification and approximation inherent in economic theorizing.

Discrete Time Algorithms

1996
The development of algorithms for the computation of projected dynamical systems is a topic equal in importance to that of the exploration of qualitative questions of existence, uniqueness, and stability.

Discrete-Time Control

1996
In the remaining chapters of the book we will turn our attention to feedback control problems. In solving these problems, we will find that we will frequently call on the results of Chapters 1 to 7.
