elbowPlot {TopKSignal}

elbowPlot

Description

The elbow plot permits the identification of subsets of objects, e.g. top-$k$ or bottom-$q$ objects. On the x-axis all objects are ordered according to their rank positions. On the y-axis the corresponding estimated signal values are displayed. The idea of the elbow plot is to scan for 'jumps' in the sequence of ordered objects ? i.e. find signal estimates next to each other that are visually much distant - in an exploratory manner. The elbowPlot function requires the estimation results from the estimateTheta function.

elbowPlot(estimation, title = "")
