Nonparametric Regression. We have been primarily discussing parametric tests; i.e. , tests that hold certain assumptions about when they are valid, e.g. t-tests and ANOVA both had assumptions regarding the shape of the distribution (normality) and about the necessity of having similar groups (homogeneity of variance). . . conditional .

Issues related to the initial specification of theoretical models of interest. Model specification:. Measurement model:. EFA vs. CFA. reflective vs. formative indicators [see Appendix A]. I have been suffering from cancer for the last 10 years and have been so afraid. You have made it easier for me to think and talk about issues and I feel in control of the process….. I want this to end soon and I do not want to prolong my life .. need help to say this to my family.
