多元分析

The samples of the study are the bond mutual funds in Taiwan ranging from September 2000 to May 2004. First, we use student's t test to compare the difference of the rate of return in different business cycle period. Then, Spearman's coefficient of rank correlation is involved to test the performance persistence.
