Hi
is there a command that calculates the correct adjusted R-squared, when
I work without intercept? (The R-squared from lm without intercept is
false.)
Greetings

Then we need your definition of your version of correct - we know the

Hi! This answer in R-FAQ might help you:

When people say that, they are usually implying that a correct R-squared can
be
for example the same model with intercept R² = 0.6, without intercept R²
= 0.9 and higher. In my definition of R², R² has to be equal or less
without intercept
I do not know what R shows, but in the summary of the model without
intercept it does not show the R² of the regression line.

1 - crossprod(residuals(model)) / crossprod(y - mean(y))
And the reason why that is not used in R:
y- rnorm(100,10,1)
x - 1:100
model - lm(y~x-1)
1 - crossprod(residuals(model)) / crossprod(y - mean(y))
