Trivedi (2007), Regression Analysis of Count Data. For study 1, data from Days 11, 13, and 15 were examined by two-way ANOVA to the expectations of the mean squares. The independent variables included the OA status of an article, citation count, self-citation counts, number of authors, length in pages, and number of references. Data are presented as least square means (LSM) total counts with SE. We consider zero-inflated Poisson and zero-inflated negative binomial regression models to analyze discrete count data containing a considerable amount of zero observations. For the cohort of survey respondents for whom there was both baseline and follow-up data, regression analyses (general linear regression was used for continuous measures and logistic regression was used for categorical measures) tested the significance Negative binomial regression analysis (STATA command 'nbreg') compared the area daily bicycle counts between the intervention and comparison areas over time (using an interaction term) and tested for statistical differences. Third Keeping up the count doesn't give you a huge edge, but it gives you enough of an edge to tell you when to bet more or less which allows a good black jack player to slowly grind out a profit. Timmermann (2009), Disagreement and biases in inflation expectations,. Analyses examined associations between alcohol display category and (1) AUDIT problem drinking category using logistic regression, (2) AUDIT score using negative binomial regression, and (3) alcohol-related injury using the Fisher exact test . To determine what factors (indicators/data) were useful, I ran regression analysis on the various factors and looked for significant R Squared and P-Value readings to tell me what factors were actually predictive and what factors/indicators were more random and not useful. Generalised linear models: linear models as an extension of linear regression; analysis of binary data by logistic regression; analysis of counts and proportions. For both studies, effects of day on steady-state levels of endometrial PRL-R mRNA were examined by regression analysis. Immunocytochemical Analysis Frozen sections (4-8 ^m) of uterine tissues embedded in OCT compound in study 1 were cut with a cryotome (Lipshaw. Data collected were subjected to analysis with SPSS version 20 using frequency counts, percentages and probit regression analysis was used to isolate the determinants of migrant farmers' household welfare status.
