Question

the data used in the processes at your work place, identify at least five attributes with mixed types from ordinal, nominal, symmetric binary, and asymmetric binary. You may choose any combination of them, but there must be at least three types in your data chosen from the data types given above. (a) Identify the five attributes that you have chosen, their types and the possible values that these attributes may hold. In case of an ordinal variable (if you’ve chosen this data type), also provide the sequence of the possible values. For asymmetric binary variable (if you’ve chosen this data type), identify the preferred values. (b) Show your data inside a table with attribute names as columns, and the data instances as rows. Show only 5 rows. (c) Calculate the dissimilarity between any two instances, using the mixed type distance calculation method. Choose any two instances from your data table from part b of this question.

Answer 1

Kindly refer to the table below for the data inferences.

The mixed type distance method

We need to find Chi square distance between the four variables for any two samples say 1 and 2

The chi squate distance is given by
