MMA8451Q High Pass Filter Mathematical Model

In reading through the datasheet and application note AN4071, the only description of the high pass filter built into the MMA8451Q is that it is 16 Hz with an 800 Hz sample rate.  

What is the mathematical filter description of the high pass filter?  I've got a Python script to take my raw data and convert it to filtered data, but the behavior doesn't match my predictions from the model.
