1. A method of creating an analytical model, which differentiates a biological status from other biological statuses, the method comprising: entering, into a digital computer, at least a plurality of first input values associated with a first genetic element, a plurality of second input values associated with a second genetic element, and a plurality of third input values associated with a third genetic element; creating one or more intermediate values using at least the plurality of first input values associated with the first genetic element and at least the plurality of second input values associated with a second genetic element using the digital computer, wherein each intermediate value is a function of at least one or more first input values and at least one or more second input values; and creating a boundary space for the biological status using the one or more intermediate values and the plurality of third input values using the digital computer, wherein the boundary space differentiates the biological status from other biological statuses, wherein the first genetic element comprises mecA, the second genetic element comprises a Staphylococcus aureus (SA)-target gene sequence, and the third genetic element comprises SCCmec, and wherein the biological status comprises an MRSA status.
