Description Usage Arguments See Also Examples
This function calculate Sum of Squares Errors (SSE) for Triangular Fuzzy observation on the basis of m=1,2,3,... (Parchami et al., 2017, 2018).

Data |
a matrix with dim=c(n, 4) and |
m |
a positive integer number which related to the weight of distance between two cuts of fuzzy numbers, and its default is m=1. For more details see (Parchami et al., 2017, 2018). |

data(Data)
sse.fuzzy( Data ) # For m=1
sse.fuzzy( Data, m=2)
# Example 2 ( Checking relation sst = sstr + sse for different m):
sst.fuzzy(Data) == sstr.fuzzy(Data) + sse.fuzzy(Data)
sst.fuzzy(Data, m=3) == sstr.fuzzy(Data, m=3) + sse.fuzzy(Data, m=3)
for(m in 1:10)
print( round(sst.fuzzy(Data, m), 10) == round(sstr.fuzzy(Data, m) + sse.fuzzy(Data, m), 10) )
