Polynomial p-adic Low-Discrepancy Sequences
Christian Weiß
The classic example of a low-discrepancy sequence in is with and . Here we address the non-linear case and…
Tobit models for count time series
Christian H. Weiß, Fukang Zhu
Several models for count time series have been developed during the last decades, often inspired by traditional autoregressive moving average (ARMA) models for real-valued time ser…
Mean-preserving rounding integer-valued ARMA models
Christian H. Weiß, Fukang Zhu
In the past four decades, research on count time series has made significant progress, but research on -valued time series is relatively rare. Existing -val…
Stein EWMA Control Charts for Count Processes
Christian H. Weiß
The monitoring of serially independent or autocorrelated count processes is considered, having a Poisson or (negative) binomial marginal distribution under in-control conditions. U…
A p-adic Poissonian Pair Correlation Concept
Christian Weiss
The pair correlation statistic is an important concept in real uniform distribution theory. Therefore, sequences in the unit interval with (weak) Poissonian pair correlations have…
Control Charts for Poisson Counts based on the Stein-Chen Identity
Christian H. Weiß
If monitoring Poisson count data for a possible mean shift (while the Poisson distribution is preserved), then the ordinary Poisson exponentially weighted moving-average (EWMA) con…
