Interpreting results of utest command

[Umair khan]

Dear All,

I am testing for U-shaped relationship and ran utest. I need some help in the interpretation of the results (as I cannot find any information online). Here`s the output:
----------------------------------------------------------------------------------------
Specification: f(x)=x^2
Extreme point: 2.021296

Test:
H1: Inverse U shape
vs. H0: Monotone or U shape

-------------------------------------------------
| Lower bound Upper bound
-----------------+-------------------------------
Interval | -1.504362 5.853607
Slope | .0154643 -.0168093
t-value | 2.687749 -1.386659
P>|t| | .0036334 .0828677
-------------------------------------------------

Overall test of presence of a Inverse U shape:
t-value = 1.39
P>|t| = .0829
----------------------------------------------------------------------------------------

Many thanks or the help.

Best,
Umair

Can anyone help? I have the same question

I'm a little confused about what the question is; in #1, above, we see a null hypothesis and a p-value of 0.08 - is that what is being asked about? if not what part of the output is not clear? have you read the article (cited in the help file)?
