Estimate 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)
Arguments
- 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.
Value
standard deviation array.
