Pwcorr Stata P Value. Since this is less than 0 05 the correlation between these two variables is statistically significant. The first command generates a correlation coefficient matrix with p values.

In addition the option star p value will put the character next to correlates at or better than the specified value. Lower and star 05 requests stata to display a star with each correlation that is significant at 05 or better. Let vbe the number of variables specified so that k v v 1 2 correlation coefficients are to be estimated.
If you also want stata to let you know whether your result is statistically significant at a particular level e g where p 05 you can set this p value by adding it to the end of the code e g 05 where p 05 or 01 where p 01 preceded by sig star e g sig star 05 which places a star next to the correlation score if your result is statistically significant at this level.
The unadjusted significance level is calculated by pwcorr as p 2 ttail n 2 jˆbj p n 2 1 ˆb2 correlate correlations covariances of variables or coefficients 7. In case the researcher wants to determine if the results are significant at a specific confidence interval ex. In addition the option star p value will put the character next to correlates at or better than the specified value. I is the mean of x and y is similarly defined.
