Hierarchical linear modeling

Throughout the Bronze Age, the cultures of the Aegean civilizations showed influences in trade, religion and economic administration. The iconography of these civilizations not only revealed their culture but also how they functioned throughout Greece. Weapons and animal representations like bulls and griffins, are all characteristic of Minoan and Mycenaean civilizations. But the settings in which they are presented offer deeper implications into their values and identity. Excavated frescos,…

intervention is small and not clinically significant. Association and causality is not proven in this case. The data set given was imported to Stata and summary statistics were used and graphs and scatter plots on Stata to visualise and analyse the data. 3 A linear regression analysis was done with Stata to find the treatment effect to adjust for baseline co variates. (propensity score matching) The results are as below- weight after treatment being the dependent variable (continuous…

Performance Evaluation In order to assess the model accuracy, it is necessary to use some quantitative measures of learning. In this study the Mean Squared Error (MSE) and regression analysis were used to evaluate the model performance. MSE is a useful measure of success for numeric prediction and is calculated using Eq. (1). It is worth mentioning that small values of MSE indicate better performance of the ANN model. It was found that the optimum performance of the model is at 25 neurons with…

From there I can add a regression line, find the equation of my model and the correlation coefficient. This will indicate how strong a relationship there is between my two variables. I can also use my data to plot a residual plot to prove that a linear model is a good fit for my data.…

3.2 Developing strategies Internal Factor Analysis Summary (IFAS) Contained six factors that have been identified associated with the strengths and weaknesses in the mining management LPMED as describe in Table 1. Values for the lowest weighting is 0.1 and 0.25 to the highest, while value for little influence rating factors is 2 and 4 for a big impact factors. The total score obtained from the Internal Factor Analysis is 0.65 External Factor Analysis Summary (EFAS) With regard to opportunities…

Scatter Diagram In Figure 1, the straight line fits through the data plotted below showing that a positive linear relationship exists. The small scatter around the line shows the strong linear correlation as well as positive slope. Figure 1: Scatter diagram showing strong positive linear relationship 3. The estimated linear equation is Yi = b0 + b1X1 + e1, where Y is the estimated dependent value for the observation, X is the estimated independent variable for the…

Technology: The World We Live In What would people do without technology? Technology is the focal point of everybody’s lives. It is used everyday for work, to strengthen connections, or pay for something online. Technology has never been relied upon so much. Former Google CEO Eric Schmidt and writer Jared Cohen, in their article “Our Future Selves,” argue that technology will offer the world a greater future with the possible connections and productivity it can generate. Professor Lori Andrews…

In this work, we assume two different potentials for the initial and final heavy quarkonia and the intermediary hybrid states. The most popular potential form for the study of heavy quarkonia is the Cornell potential [11] V(r)= -κ/r + b r (2.13) Usually many authors prefer α_s (r) instead of κ. The relation between them is κ=(4α_s (r))/3 and α_s (r) can treated as constant for bb ̅ and cc ̅…

Lab 1: Fluctuating Stresses Jinyuan Zhang Due Date: Wednesday, October 14, 2015 Lab Section: 5 Objectives: There are three objectives for this lab. The first objective is applying stresses calculation on a bicycle crank shaft with real-world load. Second objective is visualization of stresses’ fluctuate in process of fatigue failure analysis. The last objective is using the stresses model to find the force is applied on the crank shaft. Sample Calculation: For collecting the…
