Basics of ARMA and ARIMA Modeling
 
11:24
ARMA/ARIMA is a method among several used in forecasting variables. Uses the information obtained from the variables itself to forecast its trend. The variable is regressed on its own past values. Based on univariate analysis. Knowing and analysing the probabilistic, or stochastic, properties of variables. Designed to forecast future movements. Uses the philosophy “let the variable speak for itself”. This concept is very relevant because it helps investors, government regulators, policy makers and relevant stakeholders take informed decision. In essence, information relating to the series are obtained from the series itself. The Box-Jenkins type time series models allow Yt to be explained by past, or lagged, values of Y itself and stochastic error terms (innovations or shocks). For this reason, ARMA models are sometimes called atheoretic models because they are not derived from any economic theory. The series is simply explaining itself using its historical data. ARMA is composed of two distinct models which explains the behaviour of a series from two different perspectives: the autoregressive (AR) models and the moving average (MA) models. We will also show that these models move in opposite directions of one another. Distinction between ARMA and ARIMA is the integration component which brings us back to the subject of stationarity. In reality, most economic variables are non-stationary hence they have to go through a transformation process called differencing before they become stationary. The transforming process is also called integration. So ARIMA informs the researcher or reader that the series in question has gone through an integration process before being used for any analysis. Hence, the moment a nonstationary variable is differenced before becoming stationary, such is known as an integrated variable. Since the essence of engaging an ARIMA model is to forecast a series, the B-J methodology uses four steps: identification, estimation, diagnostics and forecasting.

Time Series - 1 Method of Least Squares - Fitting of Linear Trend - Odd number of years
 
14:40
#Statistics #Time #Series #Business #Forecasting #Linear #Trend #Values #LeastSquares #Fitting #Odd Definitions  “A time series may be defined as a sequence of values of same variable corresponding to successive points in time.” – W. Z. Hersch  “A time series may be defined as a sequence of repeated measurement of a variable made periodically through time.” – Cecil H. Mayers Analysis of Time Series “The main object of analyzing time series is to understand, interpret and evaluate changes in economic phenomena in the hope of more correctly anticipating the course of future events.” – Hersch A time series is a dynamic distribution, which reveals a good deal of variations over time. Statistical methods are, therefore, required to analyze various types of movements in a time series. There may be cyclical variations in general business activity and there may be short duration seasonal variations. There are also some accidental and random variables. The primary purpose of the analysis of time series is to discover and measure all such types of variations, which characterize a time series. Time series analysis means analyzing the historical patterns of the variable that have occurred in past as a means of predicting the future value of the variable. It helps to identify and explain the following: (i) Any regular or systematic variation in the series of data which is due to seasonality- the ‘seasonal’ (ii) Cyclical patterns. (iii) Trends in the data. (iv) Growth rates of these trends. This method can be useful when no major environmental changes are expected and it does highlight seasonal variations in sales and consumer demand. However, time series analysis is limited when organizations face volatile environments. Components of Time series – The time series are classified into four basic types of variations which are analyzed below: T = Trend S = Seasonal variations C = Cyclic variations I = Irregular fluctuations. This composite series is symbolized by the following general terms: O = T x S x C x I Where O = Original data T = Trend S = Seasonal variations C = Cyclic variations I = Irregular components. This Multiplicative model is to be used when S, C, and I are given in percentages. If, however, their true (absolute) values are known the model takes the additive form i.e., O=T+C+S+I. Algebraic Method For Finding Trend (Method of curve fitting by the principle of Least Squares) Fitting of Linear Trend Let the straight line trend between the given time series values (y) and time (x) be given by the standard equation: y = a + bx Then for any given time ‘x’ the estimated value of ye as given by the equation is ye = a + bx The following two normal equations are used for estimating 'a' and 'b'. Σy = na + bΣx Σxy = aΣx + bΣx^2 When Odd No. of Years, [X = (Year – Origin) / Interval] Case Given below are the figures of sales (in '000 units) of a certain shop. Fit a straight line by the method of least square and show the estimate for the year 2017: Year: 2010 2011 2012 2013 2014 2015 2016 Sales: 125 128 133 135 140 141 143 Time Series, Linear Trend, Method of Least Squares, Statistics, MBA, MCA, BE, CA, CS, CWA, CMA, CPA, CFA, BBA, BCom, MCom, BTech, MTech, CAIIB, FIII, Graduation, Post Graduation, BSc, MSc, BA, MA, Diploma, Production, Finance, Management, Commerce, Engineering , Grade-11, Grade- 12 - www.prashantpuaar.com

007 How to Forecast using Time Series Analysis
 
09:22
In this video I show you how to forecast using Time Series Analysis. I use the Additive Method where y = t + s. The example I use is a Google keyword search on the term 'ice cream'. It is expected that this search term is cyclical, which is perfect for time series analysis. This is due to the seasonal nature of ice cream consumption or on-line search. Firstly, I calculate the seasonal variation and then the adjusted seasonal average. This is required so that I can use these seasonal average figures to represent the likely seasonal figures for the following year that I'm forecasting. Secondly, I estimate the trend. Once the trend is estimated, the data for the following year can be forecasted using the above formula.

So, lets deep dive into this video and understand what is time series and how to implement time series using R. Below topics are explained in this " Time Series in R Tutorial " - 1. Introduction to ARIMA model 2. Auto-correlation & partial auto-correlation 3. Use case - Forecast the sales of air-tickets using ARIMA 4.

Working with Time Series Data in MATLAB
 
53:29
See what's new in the latest release of MATLAB and Simulink: https://goo.gl/3MdQK1 Download a trial: https://goo.gl/PSa78r A key challenge with the growing volume of measured data in the energy sector is the preparation of the data for analysis. This challenge comes from data being stored in multiple locations, in multiple formats, and with multiple sampling rates. This presentation considers the collection of time-series data sets from multiple sources including Excel files, SQL databases, and data historians. Techniques for preprocessing the data sets are shown, including synchronizing the data sets to a common time reference, assessing data quality, and dealing with bad data. We then show how subsets of the data can be extracted to simplify further analysis. About the Presenter: Abhaya is an Application Engineer at MathWorks Australia where he applies methods from the fields of mathematical and physical modelling, optimisation, signal processing, statistics and data analysis across a range of industries. Abhaya holds a Ph.D. and a B.E. (Software Engineering) both from the University of Sydney, Australia. In his research he focused on array signal processing for audio and acoustics and he designed, developed and built a dual concentric spherical microphone array for broadband sound field recording and beam forming.

Seasonal Decomposition and Forecasting, Part I
 
05:59
(Index: https://www.stat.auckland.ac.nz/~wild/wildaboutstatistics/ ) How big is the seasonal effect? We’ll discuss two models for decomposing a basic time series plot by separating out the trend, seasonal effect and residuals. After you’ve watched this video, you should be able to answer these questions •What is the basic idea behind an additive model (or additive seasonal decomposition)? •Why do we want to find stable structures in our time series?
