An example of an AI chatbot conversation about testing normality of residuals in regression analysis.
How do I test the normality of residuals in my regression model?
You can test the normality of residuals using several methods, such as the Shapiro-Wilk test, Q-Q plots, or histograms.
What is the Shapiro-Wilk test?
The Shapiro-Wilk test is a statistical test that checks if a sample comes from a normally distributed population.
How do I perform a Q-Q plot?
To create a Q-Q plot, you plot the quantiles of your residuals against the quantiles of a normal distribution. If the points form a straight line, the residuals are normally distributed.
Are there any software tools that can help with this?
Yes, software like R, Python (with libraries like SciPy and Matplotlib), and SPSS can help you perform these tests easily.
