next generation path modeling Welcome to the SmartPLS Community, SmartPLS is a software application for (graphical) path modeling with latent variables (LVP). The partial least squares (PLS)-method is used for the LVP-analysis in this software. Hawthorne effect Aerial view of the Hawthorne Works, circa 1920. History[edit] The term was coined in 1950 by Henry A. Wiki: Statistical Methods Basic statistics help: Correspondence Analysis Factor Analysis Some nice explanations: KMO and Bartlett's Test of Sphericity (Factor Analysis) The Kaiser-Meyer-Olkin measure of sampling adequacy tests whether the partial correlations among variables are small. Treatment of Missing Sata David C. Howell Missing data are a part of almost all research, and we all have to decide how to deal with it from time to time. There are a number of alternative ways of dealing with missing data, and this document is an attempt to outline those approaches. The original version of this document spent considerable space on using dummy variables to code for missing observations.

Research 3.0: driving the knowledge economy Digital technologies are rapidly changing the type of research we can tackle and the way researchers work. How will research be in future? As the key provider of the digital infrastructure for UK higher education and research, JISC is seeking answers to this question during the Research 3.0 campaign. See our Research 3.0 video8 for more about the issues we’re addressing, go to our blog9 to give your views and say what are the important issues for you, or see what others are saying. Cluster Analysis R has an amazing variety of functions for cluster analysis. In this section, I will describe three of the many approaches: hierarchical agglomerative, partitioning, and model based. While there are no best solutions for the problem of determining the number of clusters to extract, several approaches are given below.

SPSS Learning Module: Using SPSS functions for making and recoding variables SPSS Learning Module Using SPSS functions for making and recoding variables 1. Introduction SPSS has a wide variety of functions you can use for creating and recoding variables. Reliability Analysis: Statnotes, from North Carolina State Unive This content is now available from Statistical Associates Publishers. Click here. Below is the overview and table of contents in unformatted form. Overview Researchers must demonstrate instruments are reliable since without reliability, research results using the instrument are not replicable, and replicability is fundamental to the scientific method. Reliability is the correlation of an item, scale, or instrument with a hypothetical one which truly measures what it is supposed to.

PREST: Practitioner Research and Evaluation Skills Training in Open and Distance Learning: User Guide Description The PREST training resources aim to help open and distance learning practitioners develop and extend their research and evaluation skills.They can be used on a self-study basis or by training providers.The resources consist of two sets of materials: a six-module foundation course in research and evaluation skills and six handbooks in specific research areas of ODL.There is an accompanying user guide.A full list appears on the back cover. The modules and handbooks The programme consists of two sets/levels of learning materials: six core modules which, together, form a small foundation course in research and evaluation methods explored within ODL contexts; six handbooks – a collection of stand-alone interactive guides to conducting research and evaluation in a particular field of ODL. The core The core part of the PREST programme consists of six modules:

SEMNET Information The Structural Equation Modeling Discussion Network Researchers who study or apply structural equation modeling methods may be interested in an electronic mail network called SEMNET. Operating over the Internet, SEMNET is an open forum for ideas and questions about the methodology that includes analysis of covariance structures, path analysis, and confirmatory factor analysis. SEMNET bridges the gaps between users, between disciplines, and between conferences. SEMNET was founded in February 1993.

Partial Least Squares Regression (PLSR) Welcome to the Partial Least Squares Regression (PLSR) start the program mirror connection PLSR statistical analysis module performs model construction and prediction of activity/property using the Partial Least Squares (PLS) regression technique [1-3]. It is based on linear transition from a large number of original descriptors to a small number of orthogonal factors (latent variables) providing the optimal linear model in terms of predictivity (characterized by the Q2 value).
