Geo-targeting Project [11-25]

---

Before we start calculating the distance between the store and the customer's address, let's check if there are any missing coordinates in the SALES_Q1_LOC_POS table.

data sales_check;
set sales_q1_loc_pos;
where store_x = . or
      store_y = . or
      cust_x = . or
      cust_y = .;

keep customer_postcode store_postcode store_x store_y cust_x cust_y;
run;

Did the code fail because the input data sets don't exist?

Copy and run the code below to create the input data sets.

proc import datafile = "/folders/myfolders/Geo-targeting/Data Files/Sales_Q1.csv" out = Sales_Q1 dbms = CSV replace ; run; proc import datafile = "/folders/myfolders/Geo-targeting/Data Files/locations.csv" out = locations dbms = CSV replace ; run; proc import datafile = "/folders/myfolders/Geo-targeting/Data Files/postcode.csv" out = postcode dbms = CSV replace ; run; proc sql; create table sales_q1_loc as select a.*, b.os_x as store_x, b.os_y as store_y from sales_q1 a, locations b where a.store_postcode = b.postcode; quit; proc sql; create table sales_q1_loc_pos as select a.*, b.os_x as cust_x, b.os_y as cust_y from sales_q1_loc a left join postcode b on a.customer_postcode = b.postcode; quit;

The data step above checks if there are any missing coordinates.

It turns out there are more than 9000 records that are missing the CUST_X and CUST_Y coordinates.

Can you figure out why these coordinates are missing?
