Convex Analysisの二,三の進展について

Exploring and identifying structure is even more important for multivariate data than univariate data, given the difficulties in graphically presenting multivariate data and the comparative lack of parametric models to represent it. Unfortunately, such exploration is also inherently more difficult.

Literature review of deteriorating inventory models by key topics from 2012 to 2015

This paper develops and applies a novel test of the Holt, et al(1961) linear quadratic inventory model It is shown that a central property of the model is that a certain weighted sum of variances and covariances of production, sales and inventories must be nonnegative The weights are the basic structural parameters of the model The model may be tested by seeing whether this sum in fact is nonnegative When the test is applied to some non-durables data aggregated to the two-digit SIC code level, it almost always rejects the model, even though the model does well by traditional criteria
