Explanation correctly and in detail Q)What are the uses for hierarchical multiple regression

[Regression Analysis] How do you solve this? thanks

us the least-squares regression method to solve for accidents in May.

a regression analysis on a set of data (with two variables, X and Y) outcomes a value of r-square = 78.5What would be the interpretation of this value?

SER and R2 are “measures of fit” for a regression. Explain how SER measures the fit of a regression. What are the units of SER? Explain how R2 measures the fit of a regression. What are the units of R2?

study investigated how the content of vitamin A in carrots is affected by the time being cooked. In this example: X represents the amount of time, in minutes, that the carrot slices were cooked Y represents the content of vitamin A (in milligrams) in the carrot slices   The least-squares regression equation for this relationship is:  Y = 22.4 – 0.65X Using the regression equation, predict the vitamin A content (in milligrams) for a carrot slice that was cooked for 15 minutes. Provide your answer as a numeric value rounded to two decimal places.
