    In Japan, population has steadily concentrated in some urbanized areas. Especially, since 1960, excessive concentration of population in urban areas and strong regional dilution of population in rural areas were found. Two models, Model I and Model II were constructed for explaining the mechanism of the regional variation of population in Japan which appeared in recent years.
    The two models were applied to the actual data obtained by 4 types of regional divisions for the time periods from 1960 to 1965 and 1965 to 1970. Goodness of fit of the models to the data was statistically examined. We could find that Model I was successfully applied to the data.
    According to the results, it was concluded that the mechanism of the variation of regional population in Japan could be explained by Model I.

  • SOME APPLICATION OF MULTIVARIATE STATISTICAL ANALYSIS IN SAMPLE SURVEYS
    An Attempt to Reduce the Load of Surveyees

    While the multivariate statistical analysis has been applied to almost all fields which require some of statistical inferences, it has seldom been only to social statistical surveys, each of which always deals with many variates simultaneously, except the ratio estimate. In these years, the number of statistical surveys carried out by various agencies is steadily increasing, and items of a survey are also increasing in number and becoming complicated. Each of these facts may mean a steady increase of the load of surveyees who would not find any benefit directly from the survey, and may consequently raise the frequency of undesirable activities of surveyees. In these circumstances, it may be very necessary to reduce their load. The new method I have proposed in this paper aims at the reduction of the load of surveyees by allocating survey items partially to each surveyee through a plan such as BIB design in order to apply the multivariate statistical method for estimating parameters required.

  • ON ESTIMATING THE LOCATION GAP OF TWO NORMAL POPULATIONS BASED ON RANKED DATA

    Estimation of the normalized location difference θ=(θx-θv)/σ, σ>0 of two normal populations N(θx, σ2) and N(θv, σ2)based on ranked data is studied. Pairs of abservations (Xi, Yi), (i=1, 2, …, n) are drawn from these populations and are replaced by ranked data (r(Xi), r(Yi)) (in our case 0-1 data) at each observation. Our statistic applied in this paper is based on these ranked data and several properties of this statistic are investigated.

  • Polimetrics: Some Problems and Prospects

    In this article the author reviews important works in polimetrics and discusses some major problems which he believes polimetricians must cope withsquarely. Three problems of major importance in furthering polimetrics as one of the fields of study in the social sciences are the following: first, the problem of operationalization of concepts; second, the problem of strong inference or the problem of establishing relationships between variables most efficiently; third, the problem of modelling social systems as complex adaptive systems possessed of a self-restructuring property. His discussion covers more than fourteen works in diverse methodological traditions which have attempted seriously to cope with or even to overcome these methodological difficulties. On the basis of this discussion, the three problems are assessed, and some prospects for further development of polimetrics are suggested from the basic perspective that the cardinal aim of polimetrics is to contribute to better and deeper understanding of political phenomena.
