Linear and Nonlinear Modeling)軟體，包含線性和非線性部分，HLM可以讀取大部份統計軟體的檔案如
SPSS, SAS, SYSTAT及STATA等等。HLM常用於社會科學和行為科學，因為它常有巢狀結構(Nested
Generalized Linear Models (HGLM)和Hierarchical
Multivariate Linear Models (HMLM)等。
7 includes an improved interface, HTML output, and new statistical
features such as cross-classified random effects for linear models
for three-level data, and linear and nonlinear models for four-level
7 offers unprecedented flexibility in modeling multilevel and
longitudinal data. With the same full array of graphical procedures
and residual files along with the speed of computation, robustness
of convergence, and user-friendly interface of HLM 6, HLM 7
highlights include three new procedures that handle binary, count,
ordinal and multinomial (nominal) response variables as well as
continuous response variables for normal-theory hierarchical linear
Four-level nested models:
Four-level nested models for cross-sectional data (for example,
for item response within students within classrooms within
Four-level models for longitudinal data (for example items
points within persons within neighborhoods).
Four-way cross-classified and nested mixtures:
Repeated measures on students who are moving across teachers
within schools over time, or item responses nested within
who are cross-classified by country of origin and country of
Repeated measures on persons who are simultaneously living in a
neighborhood and attending a given school.
Hierarchical models with dependent random effects:
Spatially dependent neighborhood effects.
Social network interactions.
7 also offers new flexibility in estimating hierarchical generalized
linear models through the use of Adaptive Gauss-Hermite Quadrature (AGH)
and high-order Laplace approximations to maximum likelihood. The AGH
approach has been shown to work very well when cluster sizes are
small and variance components are large. the high-order Laplace
approach requires somewhat larger cluster sizes but allows an
arbitrarily large number of random effects (important when cluster
sizes are large)
