Is the Vote Against Adhesion of Switzerland to the European Economic Area Really the Beginning of a Divided Switzerland? Distinguished Visiting Professor Yadolah Dodge, Neuchatel University, Switzerland Date: November 28, 2010 Time: 1:00pm to 2:00pm Place: Room 1044 SSE – Mathematics and Actuarial Science Seminar Room Abstract On the 6th of December, 1992, the Swiss population voted against the “Adhesion of Switzerland to the European Economic Area”. Swiss German cantons, except the Basel-City and Basel-Land, voted against, and all French speaking cantons voted in favor of adhesion. Shocked by this outcome, the media, the politicians, and the population itself took this date as the beginning of the divided Switzerland. The purpose of this article is to show that what happened on that day was not a new phenomenon but was in line with more than a century of voting. Thoughts on the Use of the Correlation Coefficient A Public Lecture by Distinguished Visiting Professor Yadolah Dodge, Neuchatel University, Switzerland Date: November 29, 2010 Time: 1:00pm to 2:00pm Place: Room 1044 SSE – Mathematics and Actuarial Science Seminar Room Abstract Under the hypothesis of the existence of linear relationship between two random variables, new formulas are introduced to express the coefficient of correlation. One of these formulas, the fourth power of the correlation coefficient is used to determine the direction of dependency between two random variables. Also an interpretation of the correlation coefficient as an asymmetric function of kurtosis coefficient and skewness coefficient of dependent variable and independent variable is provided. In the absence of the intercept in linear regression, the correlation coefficient is also expressed as a ratio of coefficients of variation between independent and dependent variables.
