## Regression line – Fitting a line to data

Regression line – Fitting a line to data. If the scatter plot shows a clear linear pattern: a straight line through the points can describe the overall pattern Fitting a line means drawing a line that is as close as possible to the points: the “best” straight line is the regression line.

## Line Fitting

Line Fitting. Line fitting is key to investigating experimental data and calibrating instruments for analysis Common assessment of how well a line ‘fits’ is the R 2 value – 1 is perfect, 0 is no correlation. Data Quality.

## Fitting Regression Models

Fitting Regression Models. It is usually interesting to build a model to relate the response to process variables for prediction, process optimization, and process control A regression model is a mathematical model which fits to a set of sample data to approximate the exact appropriate relation

## Linear Regression

Linear Regression. How do you predict the outcome of a horse race? How do you choose a “winning” stock?. Linear Regression. Can we calculate values of one variable from another? e.g., race performance from lifetime race earnings? or, future salary from beginning salary?

Linear Regression. Handbook Chapter . Experimental Testing. Data are collected, in scientific experiments, to test the relationship between various measurable quantities that are predicted by a hypothesis, either to support or invalidate the hypothesis.
