## multiple regression? [General Statistics]

Hi ElMaestro,

nice setup. Given

» […] a lot of knobs and buttons and sliders that allow me to tweak combinations of:

» - Tesla coil zap modifier strength

» - Evil discharge combobulator intensity

» - Ion stream barbaric voltage gain

» - Apocalyptic wolfram anode ray modulation

» ...and so forth.

I’m I right that you are aiming at multiple regression (i.e., >1 regressor and and one regressand)? See there for an arsenal of methods. For the

I’m I right that you are aiming at multiple regression (i.e., >1 regressor and and one regressand)? See there for an arsenal of methods. For the

*same*number of regressors the adjusted R^{2}takes the number of data points into account.`x1 <- rnorm(10)`

y1 <- x1*2+rnorm(10, 0, 0.1)

muddle1 <- lm(y1 ~ x1)

R2.adj1 <- summary(muddle1)$adj.r.squared

x2 <- x1[-1] # drop 1

y2 <- y1[-1] # drop 1

muddle2 <- lm(y2 ~ x2)

R2.adj2 <- summary(muddle2)$adj.r.squared

cat(R2.adj1, R2.adj2, "\n")
