y= bx + a-linear equation (equation for a straight line) -a= intercept (predicted point when x=0) -b= the slope of the line Functions of Regression-predicting outcomes -must have at least two variable (predictor, outcome) -predictor and moderator help estimate dependent variable Line of best fit-Line that minimizes the difference between predicted Y (Y-hat) and the actual Y we observed -This is called the least squares criterion -judges central tendency within scattered linear distribu...

ISYE 6501 - Midterm 2 Questions and Answers 100% Correct when might overfitting occur when the # of factors is close to or larger than the # of data points causing the model to potentially fit too closely to random effects Why are simple models better than complex ones less data is required; less chance of insignificant factors and easier to interpret what is forward selection we select the best new factor and see if it's good enough (R^2, AIC, or p-value) add it to our model and fit the mod...

Geology Lab Exam II Questions and Answers 2024 with Complete Solution. A topographic map has a ratio scale of 1:250,000.

KHAN ACADEMY ALGORITHMS LIST 2024 WITH COMPLETE SOLUTION A statistician developed this procedure to calculate the "variance" of a list of numbers. The variance is a statistical quantity that corresponds to the average of the sum of the squared differences of each number from the mean. As input, the procedure takes a list of numbers and its mean: PROCEDURE calculateVariance(numbers, mean) { count ← 0 sumSquaredDiffs ← 0 FOR EACH num IN numbers { diff ← (num - mean) squaredD...

regression equation Ans- An equation used to model the relationship between the response and explanatory variables in a regression. extrapolate Ans- Using information from a data set to make predictions about data outside of the original set. significant difference Ans- A measurable difference between two groups or samples that reflects a real difference, rather than the difference being by chance. sampling frame Ans- The list of all people or things that may be included in the stat...
