Computes feature of a time series based on tiled (non-overlapping) windows. Means or variances are produced for all tiled windows. Then stability is the variance of the means, while lumpiness is the variance of the variances.
var_tiled_var(x, .size = NULL, .period = 1)
var_tiled_mean(x, .size = NULL, .period = 1)a univariate time series
size of sliding window, if NULL .size will be automatically chosen using .period
The seasonal period (optional)
A numeric vector of length 2 containing a measure of lumpiness and a measure of stability.
