Simple linear regression fits a straight line to a set of data points. Simple Linear Regression refers to the case of linear regression where there is only one X (explanatory variable) and one continuous Y (dependent variable) in the model. There you will find formulas, references, discussions, and examples or tutorials describing the procedure in detail. If you would like to examine the formulas and technical details relating to a specific NCSS procedure, click on the corresponding ‘’ link under each heading to load the complete procedure documentation. This page is designed to give a general overview of the capabilities of the NCSS software for regression analysis. NCSS has modern graphical and numeric tools for studying residuals, multicollinearity, goodness-of-fit, model estimation, regression diagnostics, subset selection, analysis of variance, and many other aspects that are specific to type of regression being performed. NCSS makes it easy to run either a simple linear regression analysis or a complex multiple regression analysis, and for a variety of response types. Regression analysis refers to a group of techniques for studying the relationships among two or more variables based on a sample.

If you are already familiar with these skills, we are confident that you will enjoy furthering your knowledge and skills in Statistics for Public Health: Logistic Regression for Public Health.NCSS software has a full array of powerful software tools for regression analysis. If you are unfamiliar with these skills, we suggest you review Statistical Thinking for Public Health and Linear Regression for Public Health before beginning this course.

This course builds on skills such as hypothesis testing, p values, and how to use R, which are covered in the first two courses of the Statistics for Public Health specialisation.

Run simple and multiple logistic regression analysis in R and interpret the outputĮvaluate the model assumptions for multiple logistic regression in Rĭescribe and compare some common ways to choose a multiple regression model That said, much of what is covered in this course is true for logistic regression when applied to any data set, so you will be able to apply the principles of this course to logistic regression more broadly too.īy the end of this course, you will be able to:Įxplain when it is valid to use logistic regression Additionally, the interpretation of the outputs from the regression model can differ depending on the perspective that you take, and public health doesn’t just take the perspective of an individual patient but must also consider the population angle. Like the others in the series, this is a hands-on course, giving you plenty of practice with R on real-life, messy data, with predicting who has diabetes from a set of patient characteristics as the worked example for this course. Why logistic regression for public health rather than just logistic regression? Well, there are some particular considerations for every data set, and public health data sets have particular features that need special attention.
