They used a PC matrix of observed data at country level and then, as noted, imputed trade flows for each individual pair of zones.

Computationally, this technique is equivalent to low rank approximation of the matrix of observed variables.

The parameters of T are therefore estimated by the 4 × 4 matrix of observed nucleotide point-mutations n ij.

Y is the response vector (breast cancer diagnosis), and X is the matrix of observed data (protein levels).

c0 is a scalar representing a hospital's cost level, i is a column vector of 1s and C is the n × 1 matrix of observed costs.

Here Y is the J × n matrix of observed blood glucose measurements; Φ is the J ×  K matrix of the values of the K basis functions evaluated at times t j, and the J ×  n matrix of error terms.

After each run, as shown graphically in Figure 2, a matrix, D, of observed data is generated and analysed by GLM, and the estimates (beta, standard error and z-score), obtained from the GLM fit, are stored in three distinct vectors.

Several algorithms discussed in this paper are based on the correlation matrix of the observed data.

The absolute matrix effect and extraction recovery were calculated as follows: Absolute matrix effect = (Mean peak area)set 2 ⁄ (Mean peak area)set 1. Extraction efficiency = (Mean peak area)set 3 ⁄ (Mean peak area)set 2. This post-extraction spike method proposed by Matuszewski et al. [11] provides a quantitative understanding of the level of matrix effect observed for specific analytes.
