regression equation回归公式 1.According to the testing results the regression equations of the tensile strength, the prismatical compressive strength and elastic modulus of concrete as a function of compressive strength and dry density were obtained, and then were compared with the regression equations ...
The formula for intercept “a” and the slope “b” can be calculated per below. Regression analysis, as mentioned earlier, is majorly used to find equations that will fit the data. Linear analysis is one type of regression analysis. For example, the equation for a line is y = a + bX...

Scroll down to find the values a = –173.513, and b = 4.8273; the equation of the best fit line is ŷ = –173.51 + 4.83xThe two items at the bottom are r2 = 0.43969 and r = 0.663. For now, just note where to find these values; we will discuss them in the next two ...
Nonlinear regression is a mathematical model that fits an equation to certain data using a generated line. It shows association using a curve, making it nonlinear
are given on the horizontal axis, and values of the dependent variable, blood pressure, are shown on the vertical axis. The line passing through the data points is the graph of the estimated regression equation:y= 0.49x+ 42.3. Theparameterestimates,m= 0.49 andb= 42.3, were obtained using ...
