I have a question regarding the analysis of my survey data. I have created one variable of seven likert scale variables after conducting the Cronbach's alpha. Now I like to use this 'merged' variable as my dependent variable and analyse it with a number of descriptive variables which are also both likert scale and 'merged' likert scale variables. The likert scales are measures in 7 levels from strongly disagree to strongly agree.

Can I apply Ordered Logistic Regression and does someone know how to apply it? I am using STATA since that is mandatory for my thesis.

Thanks in advance!
