How to perform data flow analysis on a method to determine which method parameters affect the method's return value

[nth347]

I have a sample class:

package nth347.ifn;

import java.io.IOException;
import java.io.Serializable;

public class FnCompose implements IFn, Serializable {
    private IFn f1, f2;

    public FnCompose(IFn f1, IFn f2) {
        this.f1 = f1;
        this.f2 = f2;
    }

    public Object invokeCall(Object arg) throws IOException {
        return f2.invokeCall(f1.invokeCall(arg));
    }
}

I want to analyze the invokeCall method to determine which method parameters affect the method's return value. The result should be: the 0-parameter, which is arg of the invokeCall method affect the return value. How I can perform this kind of analysis using SootUp? I can get help from SootUp documentation :(
