Regression analysis is a statistical technique that fits a line to observed data points so that the resulting equation can be used to forecast other data points. It is useful in excess capacity and economies of scale situations. Economies of scale occur when the ratio of asset to sales will change as the size of the firm increases. Regression analysis can lead to improved financial forecasts and better information which can be used to improve management's actions. Quantitative Problem: Jasper...

Help with some data science questions Q.1 The linear regression model assumes multivariate normality, no or little multicollinearity, no auto-correlation, and homoscedasticity? Which assumption is missing from this list? (no more than 10 words) Q.2 The coefficient of correlation measures the percent change in the feature variables explained by the target variables. a) True b) False Q.3 In a linear regression model, the coefficient measures the change in Y explained by one unit-change in X. a) True b) False Q4....

Question 8 3 pts Suppose you estimate a multiple regression model using OLS and the coefficient of determination is very high (above 0.8), while none of the estimated coefficients are (individually) statistically different from zero at the 5-percent level of significance. The most likely reason for this result is: spurious regression. omitted variable bias. multicollinearity. serial correlation.
