Suppose a professor would like to use the number of hours studied to predict the exam score that students will receive in his class. He collects data for 20 students and fits a simple logistic regression model. We can use the following code in R to fit a simple logistic regression model: To determine if there is a … See more Suppose a professor would like to use the number of hours studied and the number of prep exams taken to predict the exam score that students will receive in his class.

WebHastie and Tibshirani defines that linear regression is a parametric approach since it assumes a linear functional form of f (X). Non-parametric methods do not explicitly assume the form for f (X). This means that a non-parametric method will fit the model based on an estimate of f, calculated from the model.

Web7.3 - Overdispersion. Overdispersion is an important concept in the analysis of discrete data. Many times data admit more variability than expected under the assumed distribution. The extra variability not predicted by the generalized linear model random component reflects overdispersion. Overdispersion occurs because the mean and variance ...
