explain  Regression analysis and its limations

What is basic regression? What is multiple regression? How do they both relate to Data Mining?

Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. Find the regression equation, letting the first variable be the independent (x) variable, and predict the weight of a supermodel who is 167 cm tall.   \begin{array}{c|ccccccc} \mbox{Height} & 178 & 176 & 166 & 178 & 174 & 172 & 174 \cr \hline \mbox{Weight} & 58 & 54 & 47 & 57 & 55 & 53 & 54 \cr \end{array} The regression equation is \hat{y} =   +   x . The best predicted weight of a supermodel who is 167 cm tall is   .

What are some ideas for practice problems that use the regression equation?

What needs to change in an overall problem if one wants to use linear regression?

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bone density test scores that can be used as cutoff values separating the lowest 10% and highest 10%, indicating levels that are too low or too high, respectively. Sketch the region containing the lowest 10% and highest 10%. Choose the correct graph below. OA. -Za Za Q The bone density scores are ☐ OB. -Za Za (Use a comma to separate answers as needed. Round to two decimal places as needed.) ○ C. Q Za -Za D. Q a G Za -Za

Based on the regression equation, we can Multiple Choice measure cause and effect predict the value of the independent variable given a value of the dependent variable measure the association between two variables predict the value of the dependent variable given a value of the independent variable
