A Recursive Forecasting Framework Is One Where

question 22

Multiple Choice

A recursive forecasting framework is one where

• A) The initial estimation date is fixed but additional observations are added one at a time to the estimation period
• B) The length of the in-sample period used to estimate the model is fixed so that the start date and end date successively increase by one observation
• C) The initial estimation date changes as additional observations are added one at a time to the estimation period
• D) The length of the out-of-sample period used to estimate the model is fixed so that the start date and end date successively increase by one observation

Definitions:

Trailer Lock

A security device or mechanism designed to prevent the unauthorized detachment or theft of a trailer by locking it to the towing vehicle or immobilizing its wheels.

Severe Braking

A situation where brakes are applied forcefully and suddenly, often in an emergency, to reduce vehicle speed quickly.

Brake Fade

Caused by a number of factors mostly relating to reduction in the coefficient of friction of brake friction materials. Thermal expansion of brake drums under prolonged braking tends to enlarge drum diameters, meaning that the actuation mechanisms such as slack adjusters no longer function at optimum mechanical efficiency, which makes brake fade more of a problem in drum brake systems.

Safety Pop-Off Valves

Valves designed to release pressure automatically to prevent damage or explosions in pressurized systems.
