SpMatrixCalc {knnwtsim} | R Documentation |
Generates and returns an n x n matrix by calculating the seasonal dissimilarity for each possible pair of points in a vector of seasonal periods, then converts dissimilarity matrix to a similarity matrix using 1 / (D_p + 1).
SpMatrixCalc(v, nPeriods)
v |
positive numeric vector with the seasonal periods corresponding to each point in the response series. |
nPeriods |
positive numeric value representing the maximum value |
numeric matrix of seasonal similarities for the vector v
.
