CFA allows the researchers to specify correlated measurement errors, constrain loadings or factor correlations to be equal to one another, perform statistical comparisons of alternative models, test second-order factor models, and statistically compare the factor structure of two or more groups.

With correlations around 0.50, crude group prediction may be achieved. In describing the relationship between two variables, correlations that are this low do not suggest a good relatioship. Correlations coefficients ranging from 0.65 to 0.85 make possible group predictions that are accurate enough for most purposes.

There are many types of theoretical semivariogram models. Some commonly used models are given below: Spherical model: this is only valid for 1-3 dimensions. The equation is: where . Exponential model: this is valid for all dimensions with formula: where . Gaussian model: this is valid for all dimensions with formula: where .

We use the data from Mukherjee, Feigelson, Babu, etal in “Three types of Gamma-Ray Bursts (The Astrophysical Journal, 508, pp 314-327, 1998), in which there are 11 variables, including 2 measures of burst durations t50 and t90 (times in which 50% and 90% of the flux arrives). It will be used to illustrate concepts in correlation and regression.

These types ultimately take shape of a more specific form like observation of ongoing activity, observing video-taped events, self-report measures like questionnaires that can be open-ended or close-ended, Likert-type scales, interviews that are structured, semi-structured or unstructured and open-ended or close-ended.
