I read R books about scale function for variable transformation.
Acoording to this book
scale function leads me to better regression results. Or am I worng?
I hope somebody tell me about a scale function?
Is it for variable transformation?
Did you try to read
It will change the coefficients from lm and therefore their t-values but it
will not change the residuals, fitted values, R-squared, F
statistic, etc. For example, try this:
set.seed(1)
x - 1:10
y - x + rnorm(10)
lm0 - lm(y ~ x) # without scale
lms - lm(y ~ scale(x)) # with scale
