Time series analysis

Correlation analysis is used to determine the degree of relationship between variables. In correlation it is assumed that the variables mutually influence each other (Sharma, 2005). Baker and Saltes (2005) used a correlation to test capability of ABI for forecasting CS sectors and then used regression analysis’s coefficient of determination (R2) to indicate the proportion of the variance of CS that is explained by ABI. They found that non-residential CS is highly correlated with ABI in lag 5 for overall sector and 11 for commercial/industrial sector. they concluded that ABI can be used for forecasting CS as a leading indicator. They pointed out that formal structural models are needed to improve the accuracy of CS forecast. Baker, Chu, & Riskus (2014) introduced “Design Contracts” as a new leading indicator to help forecating CS. The design contracts includes information about changes in inquiries for new works including bids and requests for proposals. AIA collects data on design contracts form October 2010. They concluded that this indicator provides earlier insignt into future dedign and construction activities. There are some studies regarding forecasting of CS. None of these studies did use explanatory…

e) Time Series Analysis A time series was a sequence of data points and are often plotted via line graph. The stock market index that investors usually used, the Dow Jones Industrial Average was one of the example of time series.

A new local bakery shop is likely to use the Delphi Method by inviting a panel of experts, such as Chief Operating Officer from reputable bakeries and gourmands to forecast the future revenue of the bakery. These experts might be asked to estimate the annual revenue of the bakery and reach a general consensus after several rounds of surveys. We often use another qualitative model called Cross-Impact Analysis when estimating the likelihood of a future event occurring in relation to an earlier…

MATLAB code to create the function x^2 + 1, and evaluate that function at x = 5. The MATLAB code to create the function x^2 + 1, and evaluate that function at x = 5 is: f=@ ( x ) ( x ^ 2 +1 ) ; . ( f ( 5 ) ) the output of this function is: ans = 26 b) Write the MATLAB code to loop from 1 to 5, and evaluate the function from part a at each iteration (the first iteration will be f(1), second f(2), etc.). You can use the looping variable as an argument to be passed to f. The MATLAB…

The arm was distorted and had a series of rectangular shapes to form the arm, which bass considered to represent drug addiction. Preminger however disagreed with Bass over which animated sequence with the arm looked the best. Bass argued that “the sequence fell flat without animation” but Preminger disagreed. The official compromise was “staccato-like movements as the arm segments maneuvered through the visual progression”. After this compromise, the sequence went down as a classic in American…

This ignominy resembles the corruption in the real world, referring to the gangsters and mafias, at the time of the…

He entertains his readers with the difference between the sexes giving examples he has experienced in his own life; men and women’s instincts are different. Two of the points he really focuses on are women’s awareness of dirt (220) and men’s sensitivity to sports (221). Women can see dirt that men can’t see at all which makes them exceptionally bad at…
