The focal variables, pre-purchase interactions, post-purchase interactions, service requests, and service complaints, are incorporated as time-varying covariates that account for changes on a daily basis.

The final sample with analyzable answers for all of the focal variables consisted of 170 professors, 833 scientific employees, and 213 non-scientific employees (2 participants did not indicate their affiliation with one of these groups).

We choose a parametric Weibull hazard model formulation to account for the baseline trend of the upselling likelihood during the customer lifetime and to allow for a time-varying formulation of our focal variables, pre- and post-purchase interactions, service requests, and service complaints (Grewal et al. 2004; Kamakura et al. 2004).

These groupings allow comparison of 'current', 'previous', and 'no history of self-injury' groups on all focal variables.

Expert writing Tips

Best practice

When writing scientific papers, clearly define your "focal variables" early on to provide context for your readers.

Common error

Don't assume readers know which variables are "focal". Always specify what they are, even if you've mentioned them before. For instance, instead of saying "the effect on the focal variables", state "the effect on education, labor market participation, and literacy".
