Poisson Regression This page shows an example of poisson regression analysis with footnotes explaining the output. The data collected were academic information on 316 students. The response variable is days absent during the school year (daysabs)‚ from which we explore its relationship with math standardized tests score (mathnce)‚ language standardized tests score (langnce) and gender . As assumed for a Poisson model our response variable is a count variable and each subject has the same length

Exercise 27 5. In the legend beneath Figure 2[->0]‚ the authors give an equation indicating that systolic blood pressure is SBP = 43.2 + 0.17x. If the value of x is postnatal age of 30 hours‚ what is the value for Ŷ or SBP for neonates ≤1‚000 grams? Show your calculations. Y = a + bx 43.2 + 0.17(30) = 48.3 The SBP for neonates ≤1‚000 grams at 30 hours is 48.3. 6. In the legend beneath Figure 2[->1]‚ the authors give an equation indicating that systolic blood pressure is SBP = 50.3 + 0.12x
