Lecture 1: Stationary Time Series
www.asc.ohio-state.eduIt is clear that a white noise process is stationary. Note that white noise assumption is weaker than identically independent distributed assumption. To tell if a process is covariance stationary, we compute the unconditional first two moments, therefore, processes with conditional heteroskedasticity may still be stationary.

www.asc.ohio-state.eduElasticity The price elasticity of demand measures the sensitivity of the quantity demanded to changes in the price. Demand is inelastic if it does not respond much to price changes, and elastic if demand changes a lot when the price changes. • Necessities tend to have inelastic demand.

www.asc.ohio-state.eduH The velocity and angular velocity at the bottom of the ramp can be calculated using energy conservation. The kinetic energy can be written as a sum of translational and rotational kinetic energy: K tot = K tran cm + K rot rel to cm = 1 2 mv cm 2 + 1 2 Icm w 2 where w is the angular speed of the rotation relative to the center of mass and Icm ...

Properties of the Covariance Matrix
www.robots.ox.ac.ukProperties of the Covariance Matrix The covariance matrix of a random vector X 2 Rn with mean vector mx is defined via: Cx = E[(X¡m)(X¡m)T]: The (i;j)th element of this covariance matrix Cx is given byCij = E[(Xi ¡mi)(Xj ¡mj)] = ¾ij: The diagonal entries of this covariance matrix Cx are the variances of the com- ponents of the random vector X, i.e.,
