Nickel-based alloys are especially difficult to machine due to characteristics including high hardness and low thermal conductivity.
Question:
Nickel-based alloys are especially difficult to machine due to characteristics including high hardness and low thermal conductivity. The article “Multi-response Optimization Using ANOVA and Desirability Function Analysis: A Case Study in End Milling of Inconel Alloy” (ARPN J. Engr. Appl. Sci. 2014: 457–463) reports the following data on x = cutting velocity (m/min) and y = material removal rate (mm2/min) from one experiment.
a. The LSRL for this data is y = 182.7 + 3.29x. Calculate and plot the residuals against x and then comment on the appropriateness of the simple linear regression model.
b. Use se = 11.759 to calculate the standardized residuals from a simple linear regression. Construct a standardized residual plot and comment. Also construct a normal probability plot and comment.
Step by Step Answer:
To address part a of the question we need to calculate residuals for each observed xy pair using the provided least squares regression line LSRL which ...View the full answer
