请问各位高手，在运行stata 的时候，如何检验自变量和因变量的相关系数β=0？其中自变量是十年以来公司的各种数据，因变量是十年以来公司的总收益，谢谢大家了~~~~~~~~~~~~~~

即，如何运行

H0:β=0, H1: β ≠0， 命令是什么？？多谢大家了

Examples:  after single-equation estimation except anova

        . regress y age female educ region1 region2 region3 region4

        . test region1 = region2 = region3

        . test region4 = (region1+region2)/2

        . test (region1 = region2) (region3 = region4)

        . test educ=.1

        . test region1 region2 region3 region4, mtest

        . testparm region*

    In the above example, you may substitute any single-equation estimation command (such as clogit,
    logistic, logit, ologit, etc.) for regress.

Examples:  after multiple-equation estimation commands

    using mvreg as an example
        . mvreg y1 y2 y3: x1 x3 x3 site1-site3

    test y1 coefs = 0
        . test [y1]

    test y1 site coefs = 0
        . test [y1]: site1 site2 site3

    test all site coefficients are 0
        . test site1 site2 site3

    test y1 coefficients = y2 coefs
        . test [y1=y2]
        . test [y1=y2]: site1 site2 site3, mtest(bonf)

    test y1 coefs = y2 coefs = y3 coefs
        . test [y1=y2=y3]
        . test [y1=y2=y3]: site1 site2 site3

Examples:  after mlogit

        . mlogit y x1 x2 x3 site1 site2 site3

    test y=1 coefs = 0
        . test [1]

    test y=1 site coefs = 0
        . test [1]: site1 site2 site3

    test y=1 coefficients = y=2 coefs
        . test [1=2]

        . test [1=2]: site1 site2 site3

    test all site coefficients are 0
        . test site1 site2 site3

Examples:  after reg3

        . reg3 (y1 = x1 x2 x3) (y2 = x1 x3 x4) (y3 = x1 x2 x5)

    test y1 coefs = 0
        . test [y1]

    test equality common coefficients in y1, y2, y3: only x1
        . test [y1=y2=y3], common

    test equality common coefficients in y1 and y2 (x1 x3 _cons) and in y1 and y3 (x1 x2 _cons)
        . test ([y1=y2]) ([y1=y3]), common constant

Examples with testparm

    . testparm inc*

    . testparm inc*, equal equation(select)

非常感谢~~~

我还是新手~~不大看的懂，版主真的是好厉害的说~~

这是stata的help里面的

你先买本基础的书看看吧
