linear regression and testing the slope
Dear All,
First of all I would like to say I do not have much knowledge about this
subject, so most of you can find it really easy. I am doing a linear
regression and I want to test if the slope of the curve is 0. R gives the
summary statistics:
Call:
lm(formula = x ~ s)
Residuals:
Min 1Q Median 3Q Max
-0.025096 -0.020316 -0.001203 0.011658 0.044970

How to Populate List
...not having grounds for rejection does not mean that you
must accept it: a "non-signifcant" t-value is not proof that the
null hypothesis is true.
There is a good basic outline of the t-test in the Wikipedia article
"Student's t-test":

Hoping this helps,
Ted.
