I am trying to build a Python Toolbox, like in the attached example. I would like to implement an evaluation of mean like in Focal Statistics and subtraction like in Raster Calculator. In the documentation page is an example how to implement Focal Statistics, but this example is for Script Tool Wizard, not for Python Toolbox. Is there some example how to implement it and combine with raster calculator in Python Toolbox?
Below is attached my code. For now I implemented Focal Statistics, but it does not work.
Thanks in advance.

.pyt file)."""

self.tools = [MyModel]
class MyModel(object):
def __init__(self):
"""Define the tool (tool name is the name of the class)."""
self.label = "MyModel"
self.description = ""
self.canRunInBackground = True

param2.parameterDependencies = [param1.name]

return params

print gp.GetMessages()
return
