Section 9.3 - Weird series

[pcsksa5]

The first example (using the PBS dataset) doesn't run:

PBS_feat <- PBS |>

• features(Scripts, feature_set(pkgs = "feasts"))
  Error in ar.burg.default(x, aic = aic, order.max = order.max, na.action = na.action, :
  zero-variance series
  In addition: Warning messages:
  1: In optimise(lambda_coef_var, c(lower, upper), x = x, .period = max(.period, :
  NA/Inf replaced by maximum positive value
  2: In optimise(lambda_coef_var, c(lower, upper), x = x, .period = max(.period, :
  NA/Inf replaced by maximum positive value
  3: In optimise(lambda_coef_var, c(lower, upper), x = x, .period = max(.period, :
  NA/Inf replaced by maximum positive value
  4: In optimise(lambda_coef_var, c(lower, upper), x = x, .period = max(.period, :
  NA/Inf replaced by maximum positive value
  Error in ar.burg.default(x, aic = aic, order.max = order.max, na.action = na.action, :
  zero-variance series
  New names:
  • `` -> ...26
  Warning message:
  2 errors (1 unique) encountered for feature 7
  [2] subscript out of bounds

The subsequent line:
PBS_feat_nomissing <- PBS_feat |> na.omit()
... results in zero rows

You've got the wrong repository. The book is at https://github.com/robjhyndman/weird
This repository is for the weird package.

In any case, this is a bug in the feasts package that has been fixed. Please use the github version of the feasts package.
