A model can be generated ________. by using information taken from recent research in the field to predict performance, but the prediction is often inaccurate even when using data collected from the process for all possible data values, not just values within the range of data collected from the process by using data collected from the process to predict future performanceA regression model ________. fits a curve to experimental data that have been collected cannot be constructed unless all of the data collected form a perfectly straight line fits the experimental data that have been collected to a line cannot be used for making predictions
