1) Use plot of the stock return and consider the Autocorrelation Function to determine the auto-regressive structure of the data and explain why you think the return is stationary.
2) Use the information in (1) to estimate a univariate auto-regressive (AR) model of the return series (at the minimum estimate an AR(1) or AR(2) model).
3) Save the residuals from the model in (1) and use their square to run an auxiliary regression to test for ARCH.
4) Re-estimate the time series model either correcting for ARCH (using the GLS method in the lectures) or by augmenting the model by one or two dummy variables to correct for non-normality (any large shocks in the stock return).
Properties of a p-n junction The p-n junction possesses several interesting properties that have helpful applications in modern electronics. A p-doped semiconductor is compara
Characteristics of unijunction transistor: Characteristics : The static emitter characteristic of UJT at a given inter base voltage VBB in shown in fig. From fig., it is no
I would like to know the materials needed for electrostatic sprayer.
Q. Briefly Explain Energy and Power? If a charge dq gives up energy dw when going from point a to point b, then the voltage across those points is defined as v = dw/dq If
Q. Use a 4-to-1multiplexer to simulate the following: (a) NAND logic function. (b) EXCLUSIVE-OR logic function. (c) Σ m (1, 2, 4).
If the stator windings of an alternator were to be supplied by an AC of frequency f (as opposed to drawing an AC current from them as would be the case for an alternator) then
Research and recommend a sensor for a real full size conveyor system of approximately 1000mm width to detect objects of varying size passing along it. Discuss the suitability of th

The very basic specifications of a UJT are: Vbb(max) - The maximum interbase voltage that can be applied to the UJT (b) Rbb-the interbase resistance of the UJT (c) n - The
What is interfacing? An interface is a shared boundary among the devices which includes sharing information. Interfacing is the process of making two dissimilar systems communi
