Residual Analysis The concepts behind residual analysis for a multiple linear regression model are similar to those for a simple linear regression model. However‚ they are much more important for the multiple linear regression models because of the lack of good graphical representations of the data set and the fitted model. In simple linear regression a plot of the response variable against the input variable showing the data points and the fitted regression line provides a good graphical summary

3.0 Variance Analysis 3.1 Flexible-Budget Variance Analysis In Barnes Scuba Diving case‚ the main comparison for the flexible-budget variance analysis would be between the actual results and flexible budget. Static budget would not be useful for this comparison due to the different sales unit output which may result in a misleading and inaccurate result comparison. With reference to the Flexible Budget Section attached in Annex X‚ Flexible-Budget Variance for Revenues was identified to be a favourable

Sage Publications Principal Components Analysis Introduction Principal Components Analysis (PCA) attempts to analyse the structure in a data set in order to define uncorrelated components that capture the variation in the data. The identification of components is often desirable as it is usually easier to consider a relatively small number of unrelated components which have been derived from the data than

y2=form relations y5=sensory motor coordination y3=dynamometer y6= perseveration The data are recorded in the table below. Data analysis: Since these two dataset were independent and following normal distribution‚ but the variances are unknown. For this kind of case‚ we see 6 variables are measured on each sampling unit in two samples. First thing came into my mind was to conduct a hypothesis test for the difference between two
