Segmented regression

Fisman and Svensson found some evidence that corruption influences growth at the micro level. They have used the dataset which contains information on the estimated bribe payments of the firms in Uganda. Their dataset contains information from the Ugandan Industrial Enterprise Survey about 243 firms in 5 locations and 14 industries. As it was discussed before, corruption has a very secretive and uncertain nature, and therefore there have been implemented different methods in order to increase…

Successful organisations ensure that they maintain an environment which enables the full potential of their people to be realised. They also ensure that they align their staff management objectives with the organisation’s objectives. Training is an important activity undertaken to ensure employees at all levels have the necessary skills to carry out their roles effectively and to ensure the achievement of the organisations objectives. Of fundamental importance is the identification of the…

A0130036Y Method 1: Box Plot The question asks if Road Handling is part and parcel of Practicality, i.e. whether road handling is an essential component influencing/affecting another data group, practicality. Thus, road handling is taken to be the independent variable, x, and is ranked from the lowest to the highest score. The data is split into 5 groups, Group 1 and 5 containing the lowest-ranked and highest-ranked road handling scores, respectively. Group 1 2 3 4 5 Median 4.58 4.585 4.455…

Short Paragraph on A Rainy Day Question: Write a paragraph in about 100-120 words on ‘a rainy day’. You have to use the following questions in writing this paragraph: What is a rainy day? How does the sky look on a rainy day? What is the appearance of a rainy day? What do animals do on this day? What are the conditions of roads? What happens to poor people? How do students and some people spend the day? Answer: If it so happens that it rains all day long, we call it a rainy day. In such a day,…

C’mon Back Restaurant in Puerto Rico has been in operation for three years and has been a popular destination for tourists and locals in the country. To better forecast future sales and plan for future growth proprietor Theotis Jones has provided the following sales data analysis and develop a forecasting model. C’mon Back Restaurant has seen a 6% growth year over year in the first three years of operation. This is see in the adjacent chart of yearly sales per year. Looking over the data…

A. Mumford-Shah segmentation functional Mumford and Shah proposed this segmentation method based on a variational platform. Let Ω certainly be a bounded open amount of region R in addition to u_0 is preliminary image data. Segmentation of this kind of image into homogeneous items is completed via the search for a pair of components (u, K), where K is a number of contours, and u is usually a piecewise smooth approximation of u_0.The minimization of an energy functional (u, K) in a way that u…

2.3 The Interpretation of the Symbolism (4-5) ד כִּי יָמִים רַבִּים, יֵשְׁבוּ בְּנֵי יִשְׂרָאֵל--אֵין מֶלֶךְ וְאֵין שָׂר, וְאֵין זֶבַח וְאֵין מַצֵּבָה; וְאֵין אֵפוֹד, וּתְרָפִים. ה אַחַר, יָשֻׁבוּ בְּנֵי יִשְׂרָאֵל, וּבִקְשׁוּ אֶת-יְהוָה אֱלֹהֵיהֶם, וְאֵת דָּוִיד מַלְכָּם; וּפָחֲדוּ אֶל-יְהוָה וְאֶל-טוּבוֹ, בְּאַחֲרִית הַיָּמִים. {פ} 4 For the Israelites shall remain many days without king or prince, without sacrifice or pillar, without ephod or teraphim. 5 Afterward the…

6.5 Granger Causality Granger causality statistics determine whether past values of one variable helps to predict another variable. For example, if the lagged value of the independent variable X, help in predicting the value of the explanatory variable Y_(t+1), then X granger causes the Y. On the other hand, if the independent variable X does not help to predict Y, then the coefficients on the lags of X will all be zero in the reduced form Y equation. 7. Empirical results 7.1 Optimal lag…

The fundamental theorem of Calculus: The fundamental theorem of calculus asserts the interrelated properties of integration and differentiation. It says that a function when differentiated, can be brought back by integrating (anti-derivative) or a function when integrated, can be brought back by differentiation. First theorem: Let f be a function that is integrable on [a,x] for each x in [a,b], then let c be such that a≤c≤b and define a new function A as follows, A(x)=∫_c^x▒f(x)dt, if a≤x≤b.…

Strength All the data obtained from this experiment is plotted on the graph. The accuracy and precision can be determined from the graph. Based on the graph , as the line do not pass the origin , it can be deducted that the result is fairly accurate. Since there are few outliers on the graph , the precision of this graph is moderate. Accuracy of the graph is affected by systematic errors while the precision is affected by random errors. A few measures had been taken prior in getting more…
