Principal component analysis

was run to predict the wine rating from different features (fixed.acidity, volatile.acidity, citric.acid, residual.sugar, chlorides, free.sulfur.dioxide, total.sulfur.dioxide, density, pH, sulfates, alcohol) of wine in R. According to the initial analysis on the distributions of the features, many of those features are right-skewed and thus require log transformation. Forward Selection Algorithm was used to find the best predictive models for wine quality where each feature is added to the model…

Another advantage of having security within our schools is being able to identify information prior to an attack, communities across the country can effectively establish…

Literature review This chapter presents a review of current quantitative researches on teachers’ burnout and attrition rate. Studies show that the current attrition rate for the entire teachers’ population is 35% high (Struvyven& Vanthournout, 2014). Ingersoll, Merrill & Stuckey (2014) study analyzing the transformation of the American teaching forces found that the teaching force is increasingly less stable as the statistics on annual teacher attrition from 1988-1989 to 2008-2009 reveals that…

Regression Method Based on the data we collected, our expected regression equation is: Walmart revenue = β0 – β1CPI + β2CSI + β3ECOM – β4GAS + β5POP –β6INT – β7UNEMP + β8EARN Then we ran the regression on Minitab and got an actual regression equation. We used the method (i.e. five questions and nine problems) to evaluate the equation Minitab produced. For each of the nine problems, we ask five questions: What is the problem? How can I detect it? What are the consequences of the problem? What are…

subjects. Basic themes emerged after data reduction had been achieved. It had become noticeable that the narrative data which created the basic themes could be associated with the facilitator and also the inhibitors to compassion. With this type of analysis, it is vital that the main statements are identified. This research allows for the Bramley and Matiti to interpret and theorise from the whole story rather than breaking it down into categories. The research conducted reaffirmed that some of…
