ANALYSIS OF SICKNESS ABSENCE USING POISSON REGRESSION MODELS David A. Botwe‚ M.Sc. Biostatistics‚ Department of Medical Statistics‚ University of Ibadan Email: davebotwe@yahoo.com ABSTRACT Background: There is the need to develop a statistical model to describe the pattern of sickness absenteeism and also to predict the trend over a period of time. Objective: To develop a statistical model that adequately describes the pattern of sickness absenteeism among workers. Setting: University College

Chapter 5 QUESTIONNAIRE DESIGN AND SCALE DEVELOPMENT Naresh K. Malhotra‚ Georgia Institute of Technology Introduction This chapter describes the importance of a questionnaire and presents the process for developing questionnaires and observational forms. Guidelines for questionnaire construction are provided at each stage of the process. In addition‚ commonly used scaling techniques and use of questionnaires in experimentation are discussed and the design of observational forms is presented

possible. To support pressure ulcer risk assessment several standardized pressure ulcer risk assessment scales have been introduced and their application in clinical practice is recommended (Stechmiller et al.‚ 2008). one of the most common scales used in our hospitals is the Waterlow scale‚ This scale was designed by Waterlow in 1985‚ from study in elderly and acute wards (waterlow‚1985). The Waterlow Scale assigns believed to predispose patients towards developing pressure ulcers: build/weight‚ continence

Graphene is a one-atom thick monolayer of carbon atoms packed into a two-dimensional honeycomb lattice. According to science theories 70 years ago‚ 2D materials could not exist because of their thermodynamically instability. However in 2004‚ a group of scientists from the University of Manchester made what seem impossible a reality. By simply sticking bits of debris left over after splitting graphite by brute force on plastic adhesive tape and folding the tape many times‚ these scientists obtained

presented as a form of internal and external factors. A seven-item questionnaire we designed to measure communication. Two factors of face-to-face communication were investigated through the development and validation of the Interpersonal Communication Scale. External Perception defines an individual’s ability to interact with others‚ and Internal Disseverance refers to one’s desire to remove the distance between the individual‚ which they are communicating. The components of these two factors were explored

decisions with fewer errors. In this paper‚ demand estimation will be done through a regression analysis. This analysis will examine the elements that management should look at when determining demand for a product such as: price‚ competitor’s price‚ customer income‚ advertising and the cost of microwave ovens. The main objective of this paper will be to: estimate the demand function using regression analysis‚ find elasticities of demand with respect to various variables and make forecasting decisions

Correlation and Regression Assignment Problem 1. a. Explain which variable you chose as the explanatory variable and discuss why. * The explanatory variable is the height. This is because I am assuming that as height increases‚ the weight will increase as well. So the weight is the dependent variable b. Produce a scatter plot and insert the result here. * Scatter plot c. Find the equation of the regression line‚ Write it in the form of y=a+bx‚ where a is the y-intercept

Implementation of Regression Testing of Test Case Prioritization Abstract: In this paper‚ we described the regression testing of test case prioritization. Regression Testing is a significant and precious movement of the software preservation lifecycle. In that studies‚ various regression test variety and prioritization methods are available depends upon the coverage‚ specification‚ past history & risk. To categorize the cruel mistakes and get better the rate of fault detection‚ test case prioritization
