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.
