A less conservative alternative is to use the population standard deviation. To derive this from the sample standard deviation produced by Stata, multiply ar_sd by the square root of n-1/n; in our example, by the square root of 4/5.

For example, a student who studied for 10 hours and used a tutor is expected to receive an exam score of: Expected exam score = 48.56 + 2.03* (10) + 8.34* (1) = 77.2.

Lastly, latent class analysis is a more recent development that is quite common in customer segmentations. Latent class analysis introduces a dependent variable into the cluster model, thus the cluster analysis ensures that the clusters explain an outcome variable, (e.g., consumer behavior, spending, or product choice).

Dynamic panel-data models use current and past information. For instance, I may model current health outcomes as a function of health outcomes in the past— a sensible modeling. The Output Log displays the results of the analyses in a text window for editing, printing, and saving as a text file. Each time a statistical procedure is run, the results are automatically sent to the Output Log. Notes can be added to the output before printing or saving. The option to convert output to tab delimited format enables pasting.

In the loglinear model, the effect of a predictor X on the response Y is described by the XY association. In a logit model, however, the effect of X on Y is a main effect. If you are analyzing a set of categorical variables, and one of them is clearly a “response” while the others are predictors, I recommend that you use logistic.

In the Stata output (but not shown) is a list of iterations; this gives a clue as to how this magic is actually being performed. Iterations indicate that a nonlinear numerical optimization is being done behind the scenes, in this case to maximize the likelihood function. The log likelihood should be getting larger as the iterations proceed.
