Question

When performing this task, a large Durbin-Watson statistic indicates an underestimation of statistical significance. If a set of values generated by this task have covariance zero, (-5[1])are mean zero, and are homoscedastic, then a method for performing this task is optimal by the Gauss-Markov theorem. Binary classification problems are solved using the “logistic” form (10[1])of this task. (10[1])A form of this task seeks to minimize the sum of squared (10[1])residuals. (10[1])The quantity r-squared (10[1])signifies (10[1])the effectiveness of a form of this task (10[2])applied to data with a single independent variable. For 10 points, name this task in statistics whose “linear” type involves finding a line of best fit. ■END■ (10[1])

ANSWER: regression [or regression analysis; accept linear regression or simple linear regression or ordinary least squares regression or logistic regression; prompt on ordinary least squares or OLS or finding a line of best fit with “What task is that an example of?”; prompt on maximum likelihood estimation or MLE with “What task is done to produce the estimator?”]
