Problems solved by technology

The original point (scatter point) of the reach curve fitted by the current method is quite different from the point before the curve (the curve does not completely pass through the original point). The accuracy of the multi-screen integration results (Mixreach) also had a greater impact
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention relates to an arrival rate curve fitting method and device, and the method comprises the steps: obtaining a plurality of groups of monitored Internet gross evaluation points and information arrival rates with a corresponding relationship from a database as original data; screening the original data according to each group of information exposure parameters corresponding to the internet gross evaluation points and the information arrival rates with the corresponding relationship to obtain target original data; and fitting the target original data through the spline interpolation fitting model to obtain a target arrival rate curve. According to the invention, the technical problem of low fitting accuracy of the arrival rate curve in the prior art is solved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and device for fitting an arrival rate curve. Background technique [0002] With the follow-up research on the reach (arrival rate) fitting curve in the Mixreach system, it was found that in the curve generated by fitting the existing algorithm, under the same GRP (Gross Rating Points, total rating points), the original data point position Sometimes there will be a large interval gap (reach value>0.25%) when fitting the curve point with reach, which eventually leads to inaccurate mix calculation results. The existing reach curve fitting method is based on the linear regression equation implemented by the least square method, and the points of the existing original data are subjected to linear regression to fit the reach curve. The original point (scatter point) of the reach curve fitted by the current method is quite different from the point before the curve (the c...
