I am trying to determine whether an individual's opposition to genetic engineering is jointly determined with seeing a label that says "produced using GE."
I ran the wald test to "automate" the test and they are contradictory.
RHO(1,2)| -.01910 .06371 -.30 .7644 -.14396 .10577
Above is the relevant output from the bivariate probit: bivariateprobit; Lhs=z1, z2; Rh1=x1; rh2= x2$
The prob value is .76---do not reject rho>0.
I also calculated the wald test following p. E21-9 in the Limdep manual.
calc;list; waldtest=rho^/varrho; pvalue=1-chi(waldtest,1)$
That output is:
CALC] WALDTEST= 246.3811130
[CALC] PVALUE = .0000000
Calculator: Computed 2 scalar results
The output is telling me not to reject they null hypothesis that rho =0 and the Wald test is telling me to reject the null hypothesis.
