The residuals in regression estimation are estimates of error. Most commonly, the errors are assumed to be statistically independent, identically distributed and normally distributed, that is, to have a Gaussian distribution.

If these were the assumptions under which the regression was calculated then the residuals could (at least potentially) be examined for any departures from the assumptions. Usually they are plotted against the independent variable to see if there is any systematic relationship between the two sets of values. The residuals might also be tested for normality.

What is the residual for the point (36)?

A residual is defined in the context of some "expected" value. There is no information in the question regarding expected values.


How do you calculate residual standard deviation?

Residual standard deviation is calculated by first determining the residuals, which are the differences between observed values and predicted values from a regression model. Next, you square these residuals, sum them up, and divide by the number of observations minus the number of parameters estimated (degrees of freedom). Finally, take the square root of this result to obtain the residual standard deviation. This measure indicates the average distance that the observed values fall from the regression line.


How can you interpret the values of the slope?

The values of the slope of a line is a measure of the amount of change in the dependent (vertical) variable which accompanies a unit change in the ndependent (horizontal) variable.


The values an individual uses to interpret whether any action is acceptable and appropriate is called?

The values an individual uses to interpret whether any action is acceptable and appropriate are called their ethics or moral values. These values guide decision-making and behavior, influencing how one perceives right and wrong. They can be shaped by cultural, societal, and personal experiences. Ultimately, ethics serve as a framework for evaluating actions and their consequences.


When you use your regression line to predict values that are not in the sample and discovered large residual values in each prediction what can you say about your regression line?

There are several possible explanations: Leaving aside the two most obvious reasons: calculation error and attempted extrapolation, there are the following possibilities: The true relationship is non-linear. A relevant variable has been missed omitted. The observations are very variable: leading to a very large residual error. There is not enough variation in the independent (or predictive) variable so that Sxx is very small.

What is the residual value of a leased vehicle?

The residual value of a leased vehicle is the estimated worth of the vehicle at the end of the lease term. It is determined by the leasing company based on factors like the vehicle's make, model, expected depreciation, and market conditions. This value is crucial because it helps calculate the monthly lease payments, with lower residual values typically resulting in higher payments. Additionally, the residual value can influence the decision to purchase the vehicle at lease end.
