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.
