Greetings! My name is Dmitry and I have a 6-years experience of using professional statistic packages (SPSS, STATA, etc.) in social, economic and business studies (used methods: discriptive statistics, correlations, regression models, clustering, factor analysis and neural networks). Now I am a Head of marketing department in B2B company and I am using SPSS in my work every day. So I can analyze your data very qualitatively and fast (1-2 days). For a test you can send to me your data with analysis requires and I can tell you how I can analyze it. Got it? Hope for a productive cooperation! Good luck!
