R/mrs_data_proc.R
est_noise_sd.RdEstimate the standard deviation of the noise from a segment of an mrs_data object.
est_noise_sd(mrs_data, n = 100, offset = 100, p_order = 2)| mrs_data | MRS data object. |
|---|---|
| n | number of data points (taken from the end of array) to use in the estimation. |
| offset | number of final points to exclude from the calculation. |
| p_order | polynomial order to fit to the data before estimating the standard deviation. |
