WebJun 23, 2016 · I analyzed a multivariate data set (6 response variables, 21 observations for each) using redundancy analysis (RDA) in R with the vegan package. I wanted to determine which explanatory variables could best explain the variation of my 6 response variables taken together. After removing highly correlated (>0.85) explanatory variables, I still had ... WebSorted by: 13. Try this: fit <- glm (wealth_indicator ~ factor (ranking) + age_in_years + factor (ranking) * age_in_years) The factor () command will make sure that R knows that your variable is categorical. This is especially useful if your categories are indicated by integers, otherwise glm will interpret the variable as continuous.

WebMay 15, 2024 · 👉 One way to include more and more explanatory (independent) variables in the model because: R 2 is an increasing function of the number of independent variables i.e, with the inclusion of one more independent variable R 2 is likely to increase or at least will not decrease. WebThe amount of variation in the response variable that can be explained (i.e. accounted for) by the explanatory variable is denoted by R 2. In our Exam Data example this value is 37% meaning that 37% of the variation in the Final averages can be explained (now you know why this is also referred to as an explanatory variable) by the Quiz Averages. rachel celiberti anchor glass
