University aim to examine the impact of state factors‚ i.e. perceived depression‚ anxiety‚ distress‚ and somatization‚ and trait factors‚ i.e. absorption and boundary thinness‚ on nightmare frequency (NMF) as well as nightmare distress and effects within a non-clinical population. Initial expectations‚ in accordance with previous research‚ include: a correlation between severe nightmare distress and high absorption and thin boundaries; state factors‚ such as depression‚

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

QUESTIONS QUESTION 1: Run Q on the regressors: P (price)‚ I (income)‚ other variables and lagged Q to capture habit forming. Skip the first row because of the empty cell in this row. From the regression output‚ write down the estimated linear demand equation with t-statistics under the estimated coefficients. In addition‚ write down the R-square? Statistical significance of T-statistics is given by the P-values. There are three levels of significance: 1%‚ 5% and 10%. Ignore the P-values
