why is there still a need for graphical evaluation of data in R² or the coefficient of determination of the best fit line? |
|
Answer» Answer: The coefficient of determination is a COMPLEX idea centered on the STATISTICAL analysis of models for data. The coefficient of determination is used to explain how much variability of one factor can be caused by its relationship to another factor. Explanation: R-squared is a goodness-of-fit measure for linear regression models. This statistic indicates the PERCENTAGE of the variance in the dependent variable that the independent VARIABLES explain collectively. ... After fitting a linear regression model, you need to DETERMINE how well the model fits the data. |

So I had a thought, if you used a mixture of hydrogen and oxygen gas, then compressed it to the highest pressure, and then ignited the gasses with a spark. releasing a controlled explosion with force of 15,888 newtons out of 18 different exertion ports (8 on the upper back, 3 one each foot, and 1 on each hand). For a total of 286,000 newtons of upward thrust. could you theoretically make an working iron man thrusting system. Note: The above system would happen several times a second, kind of like the rpm of a car engine. |
