I would like to analyze data where the DV is citation counts and the IVs are 3 authors and 2 Journals. The data frame time is from 1994 to 2019. which is the most appropriate method for each question? :

1- the DV is counts (citations) and the IVs are nominal (3 authors and 2 journals). (see attachments).

2- DV is counts of citations' placement (2 groups) and the IVs are (3 authors and 2 journals). (see attachments).

3- DV is authors' publications (7 pub. for 2 authors and 2 pub. for an author) and the IVs are (3 authors and 2 journals). (see attachments).
