  • H do I get the "p-values" for polyserial correlation coefficients?

    I need to correlation matrix for several ordinal variables (in fact, one of them has more than 10 values, so that "polychotic" stata comand interpret it as continuous).

    The cuestion is:

    - a ) Case a: Ordinal - Ordinal. Polychoric output is "Polychoric".
    - b) Case b: Ordinal - Continuous. Polchoric output is "Polyserial". But, in this case, there isn't any "p-value" (Similar to tetrachoric, i.e. or Pearson G2 in Polychoric). Is possible to get it or to do any test?

    Details:

    polychoric SEARCH EXRD COOP PROT, verbose

    Variables : SEARCH EXRD
    Type : polyserial
    Rho = .57510669
    S.e. = .00661296

    Variables : SEARCH COOP
    Type : polyserial
    Rho = .57129919
    S.e. = .00735288

    Variables : SEARCH PROT
    Type : polyserial
    Rho = .35982063
    S.e. = .01033702

    Variables : EXRD COOP
    Type : polychoric
    Rho = .54387422
    S.e. = .00930039
    Goodness of fit tests:
    Pearson G2 = 182.9767, Prob( >chi2(41)) = 7.645e-20
    LR X2 = 177.94358, Prob( >chi2(41)) = 5.538e-19

    Thanks in advance
