Response Density SAS Statements

Specify SAS DATA step statements to execute in order to compute the final response.

The statements must create a variable named Response and reference the variable Density.

Density is the output from SAS PROC KDE and contains the kernel-smoothed density estimates based on the input values of Z. Depending on the scale of Z, you might wish to perform an additional transformation using this code.

•	For example, suppose Z contains the original spectral intensities, and you want to compute a shifted log2 response. Then a possible transformation would be Response = (log2(Density+(1/32)) + 5) * 5.

•	Alternatively, if your Z values are already log2 transformed, you might wish to work directly with the Density values.

•	The default response is Response = Density.

Refer to Base SAS documentation for additional details about SAS programming statements.
