If I am asked to state the intercept which one do I quote?

Estimate, Std error, t value or Pr(>|t|) ?

(If it makes any difference I am doing a regression using R)

Estimate, Std error, t value or Pr(>|t|) ?

(If it makes any difference I am doing a regression using R)

Code:

```
Estimate Std. Error t value Pr(>|t|)
(Intercept) 0.47637 0.69033 0.690 0.510
x -0.08073 0.11126 -0.726 0.489
Residual standard error: 1.011 on 8 degrees of freedom
Multiple R-squared: 0.06176, Adjusted R-squared: -0.05553
F-statistic: 0.5266 on 1 and 8 DF, p-value: 0.4887
```

Using summary(mymodel) as command. Are you really asking which line of output constitutes the intercept?

However if you are confused about the terms then here is some help:

Estimate

Std. Error

t value

Pr(>|t|)

Code:

```
Estimate Std. Error t value Pr(>|t|)
(Intercept) 0.47637 0.69033 0.690 0.510
x -0.08073 0.11126 -0.726 0.489
Residual standard error: 1.011 on 8 degrees of freedom
Multiple R-squared: 0.06176, Adjusted R-squared: -0.05553

Basically I have been asked to state the intercept of a certain regression. I know the intercept is where the line crosses the Y-axis. I always assumed the intercept value was the value after - (intercept) - like in your example. Yea I wish to know which line/value constitutes the intercept.

If I asked you to state the intercept of the above output what would you write?

Thanks for replying. Appreciate it.

Y ~ ß0 + ß1 X

Where ß0 is the intercept and the value after that (ß1) is the slope.

If I asked you to state the intercept of the above output what would you write?

ß0=0.47637 (p = 0.510)

Be more specific in what you ask.

Again depends, for scientific purposes this would be best:

ß0=0.47637 (p = 0.510)

ß0=0.47637 (p = 0.510)

This is for a regression in Psychology. I was looking at the impact of both between-subjects and within-subjects effects on depression. In this particular output I first dummy coded, then effect coded.

Your statement of the intercept looks very good to me. Thank you so much
