Interpretation of output

[Rachel Lim]

Dear all,

I just started using STATA hence I need help in interpreting an output.
Is the P-value in red considered p-value for trend in this case?


Source SS df MS Number of obs = 313
F(2, 310) = 6.88
Model 42.0006944 2 21.0003472 Prob > F = 0.0012
Residual 946.335311 310 3.05269455 R-squared = 0.0425
Adj R-squared = 0.0363
Total 988.336005 312 3.16774361 Root MSE = 1.7472

Rachel:
as this is not your first post, you should be aware (as per FAQ) that not using CODE delimiters when reporting what you typed and what Stata gave you back makes reading the results your Stata session difficult.
That said, ad assuming that you ran -regress-, the F-test reports the evidence that, taken jointly, your predictors differ from zero.

Dear Carlo, I am sorry! But I do not know what a code delimiter is. However, I will take note in subsequent posts.
I ran a regression: independent variable- no. of myopic parent, dependent variable- Spherical equivalent of children. How do I get a P for trend in this case?

Rachel:
I fail to get a feasibility for trend in your analysis, as you do not have any interaction between your predictors and, say, and a categorical variable (say, despite its limits, patients'age made catgorical).

Dear Carlo, thank you for your insights. I will take your advise in consideration
