 payload : {
    resultValuesMap : {
       "var1Id-var2Id" : {
          correlationCoefficient: "number",
          significance : "number",
          caseCount : "number"
       },
       "var1Id-var3Id" : {
          correlationCoefficient: "number",
          significance : "number",
          caseCount : "number"            
       },
       "var2Id-var3Id" : {
          ...
       } 
    }
 }
}

resultValuesMap maps 2 correlation variables to an object containing values for the correlation between them. The variable that was first in the correlationVariables input comes first in the key.
