We can also use Excel’s regression data analysis tool to calculate the log-linear coefficients. Using the above coding for the categorical variables the regression data analysis tool calculates the following values of the coefficients (on the right of Figure 3). ...
Two-way ANOVA is essentially an application of linear regression. The independent variables can be categorical (in which case you use dummy variables). That the dependent variable is continuous points towards linear regression, while if the dependent variable were categorical you would likely use bina...

2) I would also want to check the association of this pre- and post test results with number of other independent variables (categorical variables). DO I need the mean of each health factor reading and then run multivariate regression? or tell me any other method. ...
Hi Charles, thank you so much for your time and excellent resources. You have made a tremendous contribution to the ability of researchers. I have a multiple regression analysis with several IVs, some of which are coded because they are categorical. The DV is salary and I am using its natu...
We also look at how to quantify models accuracy, what is the meaning of F statistic, how categorical variables in the independent variables dataset are interpreted in the results, what are other variations to the ordinary least squared method and how do we finally interpret the result to find ...
A bar chart is a common type of chart that can be used to show the distribution of various categorical values, such as the number of customers or orders. For example, you could create a bar chart to show the distribution of monthly sales across your different departments....
Raw regression 3 output including interactions of continuous and categorical variables can be nigh impossible to interpret, but again Mitchell makes this a snap through judicious use of the margins and marginsplot commands in subsequent chapters. The first two-thirds of the book is devoted to cross...
variables, especially when dummy variables are used to model repeating patterns or special conditions (e.g., promotions, holidays, features, interventions) or combinations of categorical factors. For example, a model that uses dummy variables to estimate an hour-of-day effect would need 23 ...
