sg_optimal_combination {ARGOS} | R Documentation |

## Optimal Savitzky-Golay Filter Parameters Finder

### Description

This function finds the optimal parameters for the Savitzky-Golay filter by evaluating combinations of polynomial orders and window lengths.

### Usage

```
sg_optimal_combination(x_t, dt = 1, polyorder)
```

### Arguments

`x_t` |
A numeric vector or one-column matrix. The data to be smoothed. |

`dt` |
A numeric scalar. The time-step interval of the data. Default is 1. |

`polyorder` |
A numeric scalar. The order of the polynomial to be used in the Savitzky-Golay filter. If not specified, 4 will be used by default. |

### Value

A list with three elements: - sg_combinations: a matrix where each row represents a combination of polynomial order and window length tried. - sg_order_wl: a vector of length 2 with the optimal polynomial order and window length. - f_dist: a data frame with the mean squared error of the differences between the original data and the smoothed data for each combination.
