For a large number of samples with a 99% confidence interval, we can use tn-2 = 2.58. For the fluorescence data, the standard deviation of the slope is sb = 0.0409, so the slope with confidence interval b = 1.93 ±(2.58 × 0.0409) = 1.93 ±0.11. infected c section picturesNettet13. nov. 2024 · 1. The slope of linear regression is exactly what it is supposed to be. y=mx+c. The m slope gives the steepness of the regression line. There is no "better measure for the steepness of the line". This should be clear with the mathematics behind the equation of a straight line. The issue you are facing here is that of axis scaling. infected callus icd 10

"NettetKey Result: Gage Linearity P. In these results, the p-value for the slope is 0.000, which indicates that the slope is significant and that linearity is present in the measurement system. Because the linearity is statistically significant, you must use individual bias values and not the average overall bias value. " - Linearity slope
