Hello,
I run a linear regression I get the summary, e.g.:
> summary(lm.r)
Call:
lm(formula = signal ~ conc)
Residuals:
1 2 3 4 5
0.4 -1.0 1.6 -1.8 0.8
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 3.60000 1.23288 2.92 0.0615 .
conc 1.94000 0.05033 38.54 3.84e-05 ***
---
Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
Residual standard error: 1.592 on 3 degrees of freedom
Multiple R-Squared: 0.998, Adjusted R-squared: 0.9973
F-statistic: 1486 on 1 and 3 DF, p-value: 3.842e-0
I would like to call the probability of the t-test only in order to use it
separately. For example I 'd like to get:
Pr<-3.84e-05
Similarly I want to call the standard error of the parameters and the
function:
SEconc<-0.05033
I don't know how to do this. Any help?
Regards,
Ioanna
