Fit Orthogonal Report

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.

For more information about the options in the Orthogonal Fit Ratio menu, see Bivariate Fit Options. For statistical details about this fit, see Statistical Details for the Fit Orthogonal Option. For an example of this option, see Example of the Fit Orthogonal Option.
