Bayesian statistics

Jones and Holmgren (2007) presented a biomarker-adaptive parallel two-stage design to evaluate a treatment that it is thought to have different response in different subgroups defined by a prespecified biomarker positive versus negative. The idea is to run two parallel two-stage designs, one in each of the groups (biomarker-positive and biomarker-negative), and then to run an adaptive parallel design. Thus, the design begins with two parallel studies, one conducted in $N_{1}^{-}$…

1. Explain the concept of density. Density is how much matter is in the object, the atoms, and how they are arranged. It can tell others if anything sinks or not. Basically density is a measurement of atoms inside of them and how they are arranged. 2. a) Why couldn’t just the mass of a block be used to determine the identity of the block? Explain. Why couldn’t just the volume of a block be used to determine the identity of the block? Explain. If people only had the mass of the block, we can’t…

Conclusion Inheritance of drosophila from each allele from 4 of the 5 tests shows a 3:1 dominance, favouring the wild type (+) phenotype. The wild type (+) phenotype was tested and experimented on against the other eye colour phenotypes, including wild type, brown, purple, sepia and white. It was easily evident that every F1 on each test was solely wild-type dominant. Since, for example, +/+ with SE/SE can only make +/SE which can be discovered using a Punnett grid, making the first generation…

As regards alpha power analysis in our study, there was no significant difference between both groups in the alpha power values during the baseline resting eyes-closed state denoting that the resting alpha power values could not be used in evaluation of cognitive dysfunction in children with BCECTS. By presenting the target tones, the alpha power values were significantly reduced over different brain regions in the healthy control group, unlike the epileptic children who showed less reduction in…

1. What did the experiment show about how prey are selected by predators? A - Prey are selected based on accessibility, meaning ones that are the most easy to find and catch are the most susceptible. In this experiment, the moths that blended into the background were chosen less frequently than the ones that did not blend in. An example is that the white moths on a white background were chosen at a much lesser rate than newspaper moths. Three white moths and 11 newspaper moths in total (trial 1…

LEAN Exercises The Marshmallow Challenge and the PDCA cycle The Marshmallow Challenge is an interesting team building game. Not only does this silly game teach how to collaborate as a team, but, more importantly, teams that perform well, use an iterative method. In lean, small kaizens can lead the way to big changes. PDCA is an iterative process. In software development, releasing successive iterations of products are now the norm. Materials: one marshmallow, spaghetti, tape and rope.…

in four classes at a fitness club. Steinberg et al. state, “217 persons were tested during the six or seven sessions” (p. 273). Use of the word “or” makes us wonder if Steinberg et al. knew how the sampling took place. They go on to state that statistics used to prove the hypothesis were taken from those participants who attended five or more classes. Comparing this sample to the population as a whole, is inappropriate since those who felt negative moods after exercise were not likely to attend…

2. Demonstrate which tests have improved, which have gotten worse, and which have stayed the same. If any tests have gotten worse, please explain why you think this has happened. If any tests have improved, that are NOT the component that you have been working on, please explain why you think this has happened. (2) All my test have improved except my BMI and my waist-to-hip ratio. To explain, my BMI has increased by 0.2 because my weight increased due to the fact that I gained muscle mass.…

Why do Christians frequently abuse statistics? Is it to provoke shame in Christians for their “laziness”? Its main intent is to motivate Christ followers to make more disciples. Religious leaders and organizations habitually use descriptive statistics in misrepresenting and sometimes absolutely outlandish ways, usually to get attention and sound alarms, which are usually false alarms. There are good and bad forms of research. Sometimes good research is taken out of context, and then…
