Analysis Of Poisson Regression Using Spss Statistics

6. ANALYSIS OF POISSON REGRESSION USING SPSS STATISTICS 6.1. Introduction As we said earlier, Poisson regression is used to model dependent variable (consists of count data) given one or more independent variables. Dependent variable also called the outcome, response or criterion variable is the variable that we want to predict. On the other hand, independent variables also called predictors, explanatory or regressed variables are variables used to predict the value of the dependent variable. 6.2. Examples of Poisson Regression Example 1. The number of people in line in front of you at the grocery store. Predictors may include the number of items currently offered at a special discounted price and whether a special event (e.g., a holiday, a big sporting event) is three or fewer days away. Example 2. The number of awards earned by students at one high school. Predictors of the number of awards earned include the type of program in which the student was enrolled (e.g., vocational, general or academic) and the score on their final exam in math. Example 3. The number of students who catch cold at one elementary school. Predictor of the number of sicknesses might be the average weekly temperature in the area where the students live. 6.3. Description of the Data For the purpose of illustration, we have simulated a data set for Example 3 above. In this example, num_of_sickness is the outcome variable and indicates the number of sicknesses reported weekly by students at anShow MoreRelatedIBM SPSS Statistics 19 Brief Guide25880 Words   |  104 Pagesi IBM SPSS Statistics 19 Brief Guide Note: Before using this information and the product it supports, read the general information under Notices on p. 158.

We did not exclude patients admitted with an explicitly palliative care plan; this information was noted down and taken into account during the review process. During analysis, overall AE rates were corrected for the oversampling of deceased patients, because in our sample, 50% of the patients were inpatient deaths, and in reality 3%. In the results, we weight our 50% bac k to the actual 3%, so the presented results areRead MoreSwot Analysis : Stock Market5039 Words   |  21 Pageshypothesis (EMH), popularly known as the Random Walk Theory, is the proposition that current stock prices fully reflect available information about the value of the firm, and there is no way to earn excess profits, (more than the market overall), by using this information. It deals with one of the most fundamental and exciting issues in finance –why prices change in security markets and how those changes take place. It has very important implications for investors as well as for financial managers (JonathanRead MoreThe Weak-Form Efficiency of The GCC Markets7323 Words   |  30 PagesAn Empirical Analysis on The Weak-Form Efficiency of The GCC Markets Applying Selected Statistical Tests Rengasamy Elango, Mohammed Ibrahim Hussein This paper tests for market efficiency across the seven stock markets in the GCC (Gulf Co-operation Council) countries.

In addition, survey audit based on the HCWs perception, knowledge and attitude, including patient and family observation of HCWs about hand hygiene.

Conclusion: Regular cleansing of hands by HCWs reduces the risk of transmitting nosocomial pathogens between patients and thus reduce the risk of
