The models were generated using the lme4 R package (v 1.1-31) as lmer (gut environmental factor ~ factor(day) + (1 | Participant ID)); moreover, ranova function from the lmerTest package (v 3.1-3) was used to perform the random effects-likelihood ratio tests to infer whether ...
Give an example of a business situation in which you would use a one-way ANOVA. What is the independent variable? What are the levels of that variable? What is the dependent variable? What makes ANCOVA different from ANOVA? a. ANCOVA can include dummy variables. b. ...
What are the assumptions of ANOVA, and what tests are done for each assumption? Why is it helpful to analyze variations? What is an example of two-way ANOVA test and set up appropriate hypotheses? What is an error that occurs when the null hypothesis is rejected when, in realit...
Alcoholic beverages (beer, wine, spirits) are the most common dietary agents associated with headaches, with at least occasional triggering in 37% of patients3,4. Alcoholic beverages are associated with two types of alcohol-induced headaches, per the International Headache Society (IHS). First, im...
To assess the effect of the delay period on the separate parameters of the mixture model, we ran three separate, one-way ANOVAs comparing mean color bias (μ), Pm, and s.d. across conditions. Mixture model fits for the parameter μ revealed a small negative bias in each condition (...
Reduction in chlorophyll a after exposure to snail grazing was dependent on assemblage type (one-way ANOVA, P < 0.0001); low biomass Stigeoclonium tiles and tiles from the stream (on which basal cells of Stigeoclonium were dominant) were most grazer-resistant. In addition, Stigeoclonium had...

Similar rising NDVI trends were observed among land cover types, but the area trend varied (Fig. 3). There was no statistically significant difference in the NDVI trend among land cover types (ANOVA, p > 0.05), with only cropland not showing a significant NDVI trend. The areas of grassland...
Elucidate with the help of diagrams. Explain the major differences between analyzing a one-way ANOVA versus a two-factor ANOVA, and explain why factorial designs with two or more independent variables (or factors) can become very difficult to interpret Explain the term...
Anova d. Logistic Regressio Explain how to determine and interpret the standard error of estimate of a prediction equation. The work that is shown below deals with computing the standard deviation of the dataset containing the seven (7...
