...n humans, and I have approximately 1400-1800 data/time points per person (13 in total). Observations were made how the focus of neuronal activity changed spatially while processing of a frequency-modulated tone. Regression analysis was performed for each individual using orthogonal polynomials ... regtemp <- lm(tempmat[,j] ~ poly(tempmat[,1],degree=i)) ... up to degree = 5. Based on the median (i.e. over all individuals) adjusted R-square, it could be seen that a linear approach yielded about .5 adj-R2, adding a quadratic term increased R2 to about .7 (adding further terms didn't increase ad...
