Q: Can I use an equation from another article in my own?

Detailed Question -

Hello, I need to write an article to publish. I don't have any experience with statistics and econometrical models.
I would like to know if I can use another author's formula/equation for my article. The topic is more or less the same, however, the country and data change completely. I would, of course, cite the author and say that the formula is taken from him.
I would also like to know if the journals would accept an article without an original equation.

Answer:

Thank you for your question! Sure, you can use the statistical model used in other publications; however, please make sure you reference the model appropriately. Note that the model being cited is relevant in the context of your study, and that the model assumptions hold true.

While referring to an equation found from another source, place a citation number in brackets directly after its mention in the text, and then use the following notation, including the full details of the source in your reference list. For example, ‘This result matches the one obtained in [5, eq. (14)] for the preceding case’ where 5 is the source reference from where the equation has been adapted.

Hope this addresses your query. All the best for your study.
