SpletObserved Variable: a measured variable (usually used in SEM ). Outcome variable: similar in meaning to a dependent variable, but used in a non-experimental study. Polychotomous variables: variables that can have more than two values. SpletDetermination as to whether a variable is numeric or non-numeric. In one embodiment, a variable is input having a plurality of values, where each value has a count. The variable is determined to be numeric or non-numeric by assessing closeness of counts for adjacent values of the variable. Whether the variable is numeric or non-numeric is then output.
