Graduates to apply for the quantitative analysis of changes in number of graduate
students
一Topics raised
In this paper, the total number of students from graduate students (variable) multivariate analysis (see below) specific analysis, and collect relevant data, model building, this quantitative analysis. The number of relations between the school the total number of graduate students with the major factors, according to the size of the various factors in the coefficient in the model equations, analyze the importance of various factors, exactly what factors in changes in the number of graduate students aspects play a key role in and changes in the trend for future graduate students to our proposal.
The main factors affect changes in the total number of graduate students for students are as follows：
Per capita GDP - which is affecting an important factor to the total number of students in the graduate students (graduate school is not a small cost, and only have a certain economic base have more opportunities for post-graduate)
The total population - it will affect the total number of students in graduate students is an important factor (it can be said to affect it is based on source)
The number of unemployed persons - this is the impact of a direct factor of the total number of students in the graduate students (it is precisely because of the high unemployment rate, will more people choose Kaoyan will be their own employment weights)
Number of colleges and universities - which is to influence precisely because of the emergence of more institutions of higher learning in the school the total number of graduate students is not a small factor (to allow more people to participate in Kaoyan)
二 Establish Model
Y=α+β1X1+β2X2+β3X3+β4X4 +u Among them, the
Y-in the total number of graduate students (variable) X1 - per capita GDP (explanatory variables) X2 - the total population (explanatory variables)
X3 - the number of unemployed persons (explanatory variables) X4 - the number of colleges and universities (explanatory variables)
