Abstract

The present disclosure provides a data smoothing method and a data smoothing device. The data smoothing method can include: obtaining ratio data for a plurality of objects in a plurality of time periods, wherein each ratio in the ratio data is a ratio of a first variable to a second variable; calculating a mean and a variance of the ratio data based on the ratio data; determining a smoothing parameter for adjusting the first variable value and the second variable value based on the mean and the variance; and smoothing the ratio data using the smoothing parameter.
