Exploring Greek innovation activities: the adoption of generalized linear models

In this paper we examine the innovative performance of Greek firms in terms of the women participation in research and technological development. For this reason we rely on the final results of a research project on women in innovation, technology and science, based on 279 questionnaires selected on a two years time period (2004-2006). Concerning the female participation in innovations a number of variables are used, like the total number of women employees by age, by education level, by firm size and by sector, as well as women in product and in process innovations, their position in the firm (owner, manager) and finally equality in job enrichment, in salary, in education–training and in promotion. Apart of presenting the empirical results relying on the analysis of the data collected by the survey to the Greek enterprises, we use the collecting variables in an econometric formulation using logistic regression and extracting the associated probabilities for implementing innovations. For this reason, first the General Linear Model (GLIM) is introduced and statistical inference and estimation problems are discussed. Then the Logit Model is presented under the theoretical framework of the Generalized Linear Models (GLIM), while some theoretical inside is extended with a number of suggested propositions and theorems.
