# How do you find best predicted value?

## How do you find best predicted value?

If x,y are linear correlated, use the linear regression equation to find the best predicted y, . If x, y are not linear correlated, use ˉy (mean of y) as best predicted y. To find ˉy, use Statdisk/ Explore Data/ to find mean of y.

## How do I find the best predictor variable in R?

Generally variable with highest correlation is a good predictor. You can also compare coefficients to select the best predictor (Make sure you have normalized the data before you perform regression and you take absolute value of coefficients) You can also look change in R-squared value.

How do you find the predictor variable?

In secondary education settings, the equation is often expressed as y = mx + b. Where y represents the predicted variable, m refers to the slope of the line, x represents the predictor variable, and b is the point at which the regression line intercepts with the Y axis.

### Can the prediction be correct what is wrong with predicting the weight in this case?

There is nothing wrong with predicting the weight in this case.

### What is the best predicted weight of a bear with a chest size of 48 inches?

Chest size​ (inches) 58 48
Weight​ (pounds) 425 266

What is the predicted response value?

In linear regression, mean response and predicted response are values of the dependent variable calculated from the regression parameters and a given value of the independent variable. The values of these two responses are the same, but their calculated variances are different.

#### How do you find the predicted and residual value?

To find a residual you must take the predicted value and subtract it from the measured value.

#### How do you know if a predictor is significant in R?

A low p-value (< 0.05) indicates that you can reject the null hypothesis. In other words, a predictor that has a low p-value is likely to be a meaningful addition to your model because changes in the predictor’s value are related to changes in the response variable.

What is an example of a predictor variable?

Definition of a Predictor Variable More specifically, she wants to test her hypothesis that attendance can be used to predict grade point average. In this example, attendance is the predictor variable. In the example we just used now, Mia is using attendance as a means to predict another variable, grade point average.

## What is the predictor and response variables?

Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables.

## What is the best predicted weight of a bear with a chest size of 44 inches?

Intercept and Slope Estimate is the answer. The best predicted weight for a bear with a chest size of 44 inches is _262. 7_ pounds.
