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
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 0.005567 0.016950 0.328 0.750
s -0.001599 0.002499 -0.640 0.538
Residual standard error: 0.02621 on 9 degrees of freedom
Multiple R-squared: 0.04352, Adjusted R-squared: -0.06276
F-statistic: 0.4095 on 1 and 9 DF, p-value: 0.5382
what is this t-value for? The explanation in the help file was unfortunately
not clear to me. How can I test my hypotheses that if the slope is 0?
Thank you in advance,
regards,
Evrim
