The MDS Procedure

The OUTFIT= data set contains various measures of goodness and badness of fit. There is one observation for the entire sample plus one observation for each matrix. For the CONDITION=ROW option, there is also one observation for each row.

The OUTFIT= data set contains the following variables:

• BY variables, if any

• _ITER_ (if the OUTITER option is specified), a numeric variable containing the iteration number

• _DIMENS_, a numeric variable containing the number of dimensions

• _MATRIX_ or the variable in the MATRIX statement, identifying the data matrix or subject to which the observation pertains

• _LABEL_ or the variable in the ID statement, containing the variable label or value of the ID variable of the object to which the observation pertains when CONDITION=ROW

• _NAME_, a character variable containing the variable name of the object or dimension to which the observation pertains when CONDITION=ROW

• N, the number of nonmissing data

• WEIGHT, the weight of the partition

• CRITER, the badness-of-fit criterion

• DISCORR, the correlation between the transformed data and the distances for LEVEL=ORDINAL or the correlation between the data and the transformed distances otherwise

• UDISCORR, the correlation uncorrected for the mean between the transformed data and the distances for LEVEL=ORDINAL or the correlation between the data and the transformed distances otherwise

• FITCORR, the correlation between the fit-transformed data and the fit-transformed distances

• UFITCORR, the correlation uncorrected for the mean between the fit-transformed data and the fit-transformed distances
