# What Is Y Hat In Stats

### The regression line can also be used to provide the best estimate for the y value associated with an x value which is not given.

What is y hat in stats. These values show a correlation not causation between the data points. The equation takes the form where b is the slope and a is the y-intercept. The regression equation is just the equation which models the data set.

Hat is generally used to indicate an estimate of something most typically a least-squares or ML estimate but sometimes used more broadly while bar is used to indicate a mean. Courses Using This Term. And you can use your browsers commands to change the size of the text or search for key words.
