But otherwise, my R code looked very much like MATLAB. Then I read Advanced R by Hadley Wickham. I found out, while I wasn't doing...

Blackman-Tukey Spectral Estimator in R

Blackman-Tukey Spectral Estimator in R! There are two definitions of the power spectral density (PSD). Both definitions are mathematically nearly identical and define a function that describes the distribution of power over the frequency components in our data set. The periodogram PSD estimator is based on the first definition of the PSD (see periodogram post). The Blackman-Tukey...

Periodogram with R

Periodogram with R The power spectral density (PSD) is a function that describes the distribution of power over the frequency components composing our data set. If we knew the process that generated the data, we could just calculate the PSD; we would not have to estimate it. Unfortunately, in practice we won't have access to the random process, only...
