Summ (Model.A, scale= TRUE). The results came up with a note as follows: "All continuous predictors are mean-centred and scaled by 1 standard deviation" Now I have 2 questions: 1. What does 'the continuous predictors' mean? If my predictors are 3/4/5 scales, are they continuous? For example, is a Likert scale considered as continuous here? 2. I am trying to apply the same scale function in a Multi-level Model. But it is not working. Can you please suggest me, what is the problem, or what package do I need to use to get the model results with scale? I use lme4 package (lmer function).
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
Scaling the regression model results
Hi,
I used scaling
Summ (Model.A, scale= TRUE).
The results came up with a note as follows:
"All continuous predictors are mean-centred and scaled by 1 standard deviation"
Now I have 2 questions:
1. What does 'the continuous predictors' mean? If my predictors are 3/4/5 scales, are they continuous? For example, is a Likert scale considered as continuous here?
2. I am trying to apply the same scale function in a Multi-level Model. But it is not working. Can you please suggest me, what is the problem, or what package do I need to use to get the model results with scale? I use lme4 package (lmer function).
Thank you.
