Segmented regression

Total oil expenditure to Total food expenditure (R) .θ is the disturbance term, α is the intercept term and a, b, c, d, e and f are the corresponding coefficients of the independent variables. Based on the survey data obtained from 360 respondents a regression model is constructed. Ordinary Least Square Estimation technique is used to estimate the parameters. The overall significance of the model was tested using One way ANOVA (F test) which yielded an F value 49.190 and the exact probability…

co-integration is to test for stationarity of the stochastic residuals generated in the second stage of the three stage ECM procedure (Gujarati and Porter , 2009; Ogundele, 2007,Ayanwale et al 2011). Equation (3.16) will be estimated using the least square regression. This will lead us to a parsimonious error correction model which will equally be…

First we will provide some information about Malta and the uninhabited islands before discussing the instruments and the multi-criteria analysis. Malta’s land area is 316 square kilometres. The three biggest uninhabited islands are: Malta, Gozo and Comino, but there are way more. St Paul’s Island (0,101 km2), Cominotto (0,099 km2), Halfa Rock (two meters above sea-level), Old Battery’s Rock, Lantern Point Rock (height of 7 meters), Large Blue Lagoon Rock, Small Blue Lagoon Rocks, Devil’s End…

When analyzing the Red House (I 860) by William Morris and Phillip Webb in London and the Stahl llouse (I960) by Pierre Koenig, the two designs focused on symmetry in addition to a repetition of rectangular geometries. Although these houses were designed about 100 years apart they are very similar in plan. They are designed in an “L” shape. focusing on the right angles. In comparison to the Red House. the Stahl House has more refined geometries but is still designed on the basic principles that…

Evaluation Paper Description: This quantitative study uses a least-squares regression model to determine the predictive power of socio-economic factors on district-level student achievement on new, Common Core-aligned standardized assessments. We posit that educators may use our methodology and model to control for socio-economic factors, and more equitably compare school district performance. Purpose We used a least-squares regression model to determine the predictive power of socio-economic…

In the next step, the graded response IRT model will be analyzed again for each identified domain, but without the excluded items, and the model fit statistics will be assessed. If the model has a good fit statistics, the best item for each domain will be selected according to the distribution of the threshold values across the latent scale and the discrimination value; item that has threshold values cross the whole latent scale and high discrimination value will be selected. Sample Size Graded…

Temporal outliers are common trajectories that follow the populated route, but with an important difference of the speed compared to the other common trajectories. For extracting such type of outliers, we make use of the average speed used by the moving objects in the populated route, we make comparison between each sub-trajectory from the common trajectories and the average speed for all common trajectories that traverse the same route with some tolerance, and we extract two essential types;…

Figure 3 shows the voter turnout in the dataset years as the lines are representation of the countries Figure 4 shows an easier explanation of average of voter turnout for the countries in the dataset. This shows the overall to give the average turnout because figure 4 gives an understanding of this. The countries that have higher turnout are more of List PR and the lower ones are FPTP. An interesting outcome of this looking at the Scandinavian countries all have mostly higher turnout comparing…

CHAPTER 5 EXPERIMENTATION 5.1 Spur gear terms and concept Fig. 5.1 Terminology definitions for spur gears The radial distance from the pitch circle to the outside diameter is called as addendum. The radial distance between the pitch circle and the root diameter is called as dedendum. The distance of the arc along the pitch circle from one side of a gear tooth to the other is called as circular thickness. The length of the arc of the pitch circle from one point on a tooth to the same…

Introduction Conceptually, there are two general methodologies to measure frontier efficiency; the parametric approach using econometric techniques, and the non-parametric approach utilising the linear programming method. Both approaches differ mainly in how they handle the random error and the assumptions made on the shape of the efficient frontier. However, each of the techniques has its own strengths and weaknesses. The most widely employed parametric methods are stochastic frontier approach…
