make_surrogate_data | R Documentation |

This is a wrapper function for generating surrogate time series using several different null models.

make_surrogate_data(ts, method = c("random_shuffle", "ebisuzaki", "seasonal"), num_surr = 100, T_period = 1, alpha = 0)

`ts` |
the original time series |

`method` |
which algorithm to use to generate surrogate data |

`num_surr` |
the number of null surrogates to generate |

`T_period` |
the period of seasonality for seasonal surrogates (ignored for other methods) |

`alpha` |
standard deviation of seasonal cycle deviates. |

A matrix where each column is a separate surrogate with the same length as 'ts'.

data = make_surrogate_data(block_3sp$x_t)
