Assessing Poisson and Logistic Regression Models Using Smooth Tests
نویسندگان
چکیده
The smooth testing approach described in [2] has been used to develop a test of the distributional assumption for generalized linear models. Application of the test to help assess Poisson and logistic regression models is discussed. Power is compared to other common tests.

Assessment of length of stay in a general surgical unit using a zero-inflated generalized Poisson regression
Background: The effective use of limited health care resources is of prime importance. Assessing the length of stay (LOS) is especially important in organizing hospital services and health system. This study was conducted to identify predictors of LOS among patients who were admitted to a general surgical unit. Methods: In this cross-sectional study, the sample included all patien...
متن کاملVisualizing Simple Logistic Regression Models using Mosaic Plots
For categorical data, the relationship between visual displays of the data and models is not very well explored, even though for categorical data and loglinear models strong relationships do exist. Starting from assessing odds ratios visually, interaction effects of variables can be examined using mosaic plots. Cumulative link models provide a way to describe trends between ordinal variables. I...

Background and purpose: Due to the increasing information about illnesses and deaths, classified map is of appropriate methods for analyzing this type of data. Standardized infection rates are commonly used in disease mapping but had many defects. This study aimed to compare the Poisson regression models and empirical Bayes models to prepare geographical map of tuberculosis incidence in Mazanda...
متن کاملZero inflated Poisson and negative binomial regression models: application in education
Background: The number of failed courses and semesters in students are indicatorsof their performance. These amounts have zero inflated (ZI) distributions. Using ZI Poisson and negative binomial distributions we can model these count data to find the associated factors and estimate the parameters. This study aims at to investigate the important factors related to the educational performance of ...
متن کاملMultiple Approaches to Absenteeism Analysis
Absenteeism research has often been criticized for using inappropriate analysis. Characteristics of absence data, notably that it is usually truncated and skewed, violate assumptions of OLS regression; however, OLS and correlation analysis remain the dominant models of absenteeism research. This piece compares eight models that may be appropriate for analyzing absence data. Specifically, this p...
