soo i have a ratio variable(salary) and three other variables(country by hdi index, soo interval variable, and college degree type, soo nominal variable and personality(extraversion, introversion), soo another nominal variable). soo i would like too calculate salary based on all other variables. How can i do that? I can obviously calculate Pearson coefficient for country and salary, but how about for the others? What would i need to calculate, to get estimated salary based on the three variables? I hope my question is clear enough. Thanks in advance.
Simplest option is a regulard linear model, that is you are trying to predict your dependent variable salary, with your independent variables (independent between them) country, degree and personality. Note: you would really need some additional continous variables to get a better prediction.
