Time series analysis. What are the two fundamental assumptions in time series analysis? Explain in words (without writing down equations). What are the different steps in the generation of a time series using an MA(2) model. Explain just in words, the only equation that you should write down is the general equation for an MA(2) model. There is no need to write down other equations.

The em the battery is 1.5 volts, the resistance Ris 10 02. and the inductance Lis 5.0 H a) Sketch the circuit. b) Write the equations for i and di/dt as functions of time. c) Sketch the graphs of i vs. I and di/dt vs. t. d) What are the values of i and di/dt at 1 = 0 seconds just...
20.3.5 Observe and explain Observe the series of sketches at the right. The pulses travel at speed v along the string of length L. Based on your analysis and using these two quantities, decide the time interval T (called the period for the first vibration) between upward pulls of the hand so that each upward pull sup-b. ports or enhances the pulse that has just returned to and reflected from your hand after one trip down the string and back....
just question 3 2. (9 marks) This question is about infinite series. (a) Explain what it means for an infinite series Σ a, to converge to the sum L E R. (b) For the series 2ー, write down a formula for the kth partial sun 5.- (c) Using your answers to parts (a) and (b), show that Σ n'tn-1.

(b) Complete the following steps in a ‘what if’ analysis for the introduction of a ‘just in time’* form of production materials supply to a car production unit. Explanation of the Activity Area of interest Sub-systems. (*‘Just in time’ is a method of ordering and delivery of stock parts employed by a company, where the company has delivered on a regular, often daily, basis only enough parts for a short period of production. Thus capital that would otherwise be tied...

Distinguishing Between Inferences and Assumptions To be skilled in critical thinking is to be able to take one’s thinking apart systematically, to analyze each part, assess it for quality and then improve it. The first step in this process is understanding the parts of thinking, or elements of reasoning. These elements are: purpose, question, information, inference, assumption, point of view, concepts, and implications. They are present in the mind whenever we reason. To take command of our thinking, we need...
(This is the problem that you will need to spend some time on-it looks similar to one of the prep problems but the questions are different-read carefully and explain your answers thoroughly) The temperature profile of a wall with heat generation is given in the sketch below. We are only concerned with finding the constants a, b, and e for the temperature equation. As you know, we will need 3 boundary conditions to find 3 constants. 2 of these boundary...
