Positive Hypothesis Wald test

Postby ssk322 » Sun May 11, 2014 7:04 am

Hi,

I wish to conduct a positive hypothesis test within my multi-variable model through the Wald test.

For example I wish to test C(3) > 0. However I am unable to complete this action. I.e. I just want to test whether one variable within the model has a relationship greater than 0 against the dependent.

Please advise.

You will need to look up the one-tailed critical value of the t-statistic in a table.

Thank you for your swift reply.

So my critical value is 1.6529 with the DF being 190. So would I perform the Wald test C(3) = 0 and use the T-statistic produced above the F-Stat and Chi-Square?

That's right. Note that you may find the t-statistic displayed with the equation output without having to go to the Wald screen.
