[Hazel-Yi]

Instruction of mulitrun add following script in integration_demo.py

The issue was caused due to the stats.boxcox_llf function returning a float, but the code was incorrectly treating it as an array by attempting to subscript it with [0], resulting in a 'float' object is not subscriptable error
