Audit fees in auditor switching
Sarit Agami
The auditor work is examining that a company's financial statements faithfully reflect its financial situation. His wage, the audit fees, are not fixed among all companies, but can…
Correcting for Measurement Error in Segmented Cox Model
Sarit Agami
Measurement error in the covariate of main interest (e.g. the exposure variable, or the risk factor) is common in epidemiologic and health studies. It can effect the relative risk…
Improved Modeling of Persistence Diagram
Sarit Agami
High-dimensional reduction methods are powerful tools for describing the main patterns in big data. One of these methods is the topological data analysis (TDA), which modeling the…
Impact of COVID-19 on Air Quality in Israel
Sarit Agami
The COVID-19 pandemic has caused, in general, a sharp reduction in traffic and industrial activities. This in turn leaded to a reduction in air pollution around the world. It is im…
Comparison of Persistence Diagrams
Sarit Agami
Topological Data Analysis (TDA) is an approach to handle with big data by studying its shape. A main tool of TDA is the persistence diagram, and one can use it to compare data sets…
Vietoris-Rips Persistent Homology
Sarit Agami
Persistence diagrams are useful displays that give a summary information regarding the topological features of some phenomenon. Usually, only one persistence diagram is available,…
Cox Model with Covariate Measurement Error and Unknown Changepoint
Sarit Agami, David M. Zucker, Donna Spiegelman
The standard Cox model in survival analysis assumes that the covariate effect is constant across the entire covariate domain. However, in many applications, there is interest in co…
Modelling Persistence Diagrams with Planar Point Processes, and Revealing Topology with Bagplots
Robert J Adler, Sarit Agami
We introduce a new model for planar point point processes, with the aim of capturing the structure of point interaction and spread in persistence diagrams. Persistence diagrams the…
Estimation in the Cox Survival Regression Model with Covariate Measurement Error and a Changepoint
Sarit Agami, David M. Zucker, Donna Spiegelman
The Cox regression model is a popular model for analyzing the relationship between a covariate and a survival endpoint. The standard Cox model assumes a constant covariate effect a…
Modeling of Persistent Homology
Sarit Agami, Robert J. Adler
Topological Data Analysis (TDA) is a novel statistical technique, particularly powerful for the analysis of large and high dimensional data sets. Much of TDA is based on the tool o…
Modeling and replicating statistical topology, and evidence for CMB non-homogeneity
Robert J. Adler, Sarit Agami, Pratyush Pranav
Under the banner of `Big Data', the detection and classification of structure in extremely large, high dimensional, data sets, is, one of the central statistical challenges of our…
