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 same number of regressors the adjusted R² 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")
