In the Bivariate platform, use the Fit Orthogonal option to fit orthogonal regression models, including Deming regression models. An orthogonal model accounts for variability in X as well as Y.
The Orthogonal Fit Ratio table contains summary statistics for the orthogonal regression model.
Variable
The names of the variables.
Mean
The mean of each variable.
Std Dev
The standard deviation of each variable.
Variance Ratio
The variance ratio used to fit the line.
Correlation
The correlation between the two variables.
Intercept
The intercept of the fitted line.
Slope
The slope of the fitted line.
LowerCL
The lower confidence limit for the slope.
UpperCL
The upper confidence limit for the slope.
Alpha
The alpha level used in computing the confidence interval. Enter a value in the text box to change the alpha level.
