calcSWFCCentroids {geocmeans} | R Documentation |
Calculate the new centroids of the clusters based on the membership matrix (spatial version)
calcSWFCCentroids(data, wdata, belongmatrix, m, alpha)
data |
A dataframe or matrix representing the observed data with n rows and p columns |
wdata |
A dataframe or matrix representing the lagged observed data with nrows and p columns |
belongmatrix |
A n X k matrix giving for each observation n, its probability to belong to the cluster k |
m |
An integer representing the fuzziness degree |
alpha |
A float representing the weight of the space in the analysis (0 is a typical fuzzy-c-mean algorithm, 1 is balanced between the two dimensions, 2 is twice the weight for space) |
A n X k matrix representing the belonging probabilities of each observation to each cluster
