I am an academic research with major in advanced statistics and SPSS at postgraduate level. I have assisted 7 PhD (another is on going, check my profile) and many MS research projects as well as worked for 2 Australian Business firms, my responsibilities were, to organize data from various sources (i.e. Survey monkey, Previous research), Make them usable to analysis in SPSS, Excel or STATA and other analytic software, perform several analysis (i.e. Normality test, Frequency distribution, Descriptive statistics (i.e. Mean, median, mode, Std), Hypothesis testing (Chi test, U-test, T-test), Regression (linear, logistic, binary), SEM modeling, Cluster analysis, CFA, EFA and so forth). I can perform any analysis in SPSS platform and can also help to find proper way to do them. Would also interpret the results as necessary. Regarding your project my experience meets 100%, It is a binary model at multilevel, in SPSS it can be done as well as we can try multinomial-logistic regression if some independents are not dummy. Then based on the P-value we can evaluate the results, also we can determine some test to see the strength of the model. Finally, I also have some international journals based on market analysis and spss analysis results. So, can deliver you the best (check my profile feedback regarding SPSS and statistics). So let us discuss 1st, then decide. Hope to have a reply, thanks in advance, Regards; Labib [I am also having the top position as SPSS professional in this web]
