New binary variables were generated, in both Lima and Durban datasets, as follows: (i) for each allelic variant on each of the three HLA loci (HLA-A, HLA-B, and HLA-C) a binary variable was created with value 1 if the subject had that respective variant and 0 otherwise; (ii) for each OLP a binary variable was set with value 1 if the subject has responded to this OLP and 0 otherwise.
These binary variables were used to relate services and practices reported to the care setting and to demographic and socioeconomic variables.
Our binary dependent variable is set zero if no limitation is indicated and one otherwise.
This binary indicator variable is set to 1 if at least two or more proceeding days exceed the extreme temperature threshold, and 0 otherwise.
Binary variables were compared by χ test.
As for the sensor failure phenomenon, a set of binary variables is introduced to model it.
Then, the logarithmic quantization effect is transformed into the parameter uncertainty of the filtering system, and a set of binary variables is introduced to model the random measurement missing phenomenon.
If all the 56 binary variables are included in the training and test sets, the performance of both the ANN (sensitivity = 44.64%, PPV = 1.43%) and SVM (Sensitivity = 83.93%, PPV = 2.69%) is negatively affected compared to the results listed in Table 9.
We define a 3-tuple Vs =(bskip Bc), bskip(El), bskip(Eu)), where bskip Bc) is a binary variable that is set to one if Bc is a skipped MB and zero otherwise.
This model could be useful, for example, for estimating the wage premium associated with a university degree for each field of study, when the base in the binary variable b is set to high school graduates.
