Good morning reader,
I have encountered a, probably, simple issue with respect to the *formulae* of a *regression model* I want to use in my research. Im researching alliances as part of my study Business Economics (focus Strategy) at the Vrije Universiteit in Amsterdam. In the research model I use a moderating variable, Im looking for confirmation or help on the formulation of the model. The research model consist of 2 explanatory variables, a moderating variable and 1 response variable. The first explanatory variable is Culture, measured on a nominal scale and the second is Structure of the alliance, also measured on a nominal scale. The moderating variable in the relation towards Trust is Speed of Integration, measured as an interval. The response variable is Trust, measured on a nominal scale (highly likely a 5-point Likert scale). Given the research model and the measurement scales, I intent to use a ordered probit model, often used in Marketing models, to execute the regression modelling. I cant seem to find confirmation on how to model the formulae. I have been reading and studying R! for a couple of weeks now, read a lot of books from the R! series in the past, but I cant get a grasp on this seemingly simple formulae. I think I understand how to model multinomial regression (using the R-package MNP), how to execute a Principal Components Analysis and an Explanatory Factor analysis (obviously Im using a questionnaire to collect my data), but the formulae itself seems to be to simple. I expect to use the interaction symbol: "Trust~Culture + Structure : Speed_of_Integration" for the formulae, but is it really this simple? Can anybody confirm this or help me, advise me on this issue?
