Detailed Description

template<class V, class M>
class QUESO::BaseVectorSequence< V, M >

Base class for handling vector and array samples (sequence of vectors or arrays).

This class handles either vector or array samples generated by an algorithm, as well as operations that can be carried over them, e.g., calculation of means, correlation and covariance matrices.

pure virtual

Calculates the histogram of the sub-sequence. See template specialization.

The IQR is a robust estimate of the spread of the data, since changes in the upper and lower 25% of the data do not affect it. If there are outliers in the data, then the IQR is more representative than the standard deviation as an estimate of the spread of the body of the data. The IQR is less efficient than the standard deviation as an estimate of the spread when the data is all from the normal distribution. (from Matlab)

pure virtual

Selects the scales (bandwidth, scaleVec) for the kernel density estimation, considering only the sub-sequence. See template specialization.

The bandwidth of the kernel is a free parameter which exhibits a strong influence on the resulting estimate. Silverman (1986) suggests the following normal-based estimates: S1 = 1.06 × (standard deviation) × n^{-1/5} S2 = 0.79 × (iqrVec) × n^{-1/5}, where iqrVec is the interquartile range scaleVec = 0.90 × minimum(standard deviation, iqrVec /1.34) × n^{-1/5}. These estimates are popular due to their simplicity, and are used in QUESO with the adaptation of the exponent oven the sample size n (-1/5) with -1/(4 + kdeDimension) where kdeDimension is the KDE dimension.
