What is Rhat Bayesian?
What is Rhat Bayesian? Rhat refers to the potential scale reduction statistic, also known as the Gelman-Rubin statistic. This statistic is (roughly) the ratio of the variance of a parameter when the data is pooled across all of the chains to the within-chain variance. How is R Hat calculated? To find ‘r hat”s, you need […]
What nerve sends signals to brain?
What nerve sends signals to brain? There are basically two major types of nerves: sensory and motor. Sensory nerves send information such as touch, temperature, and pain to the brain and spinal cord. Motor nerves send signals from the brain back into the muscles, causing them to contract either voluntarily or reflexively. What part of […]

What are the three causes of mutation?
What are the three causes of mutation? Mutations are caused by environmental factors known as mutagens. Types of mutagens include radiation, chemicals, and infectious agents. Mutations may be spontaneous in nature. How many days is a mutation? The process takes 15 days to a month after which mutation certificate is issued. The local civic body […]
Why uniform circular motion is not SHM?
Why uniform circular motion is not SHM? Circular motion is not a form of simple harmonic motion. SHM occurs when a particle is subjected to a force that is anti-parallel to the particle’s motion. Thus, they are very different in nature. What is epoch in SHM? An epoch, in physics, refers to the displacement acquired […]
Is it good to Flex?
Is it good to Flex? It can also be a way to build strength. Muscle flexing is more accurately known as muscle contraction, because when you flex your muscles, you’re creating tension that’s temporarily making the muscle fibers smaller or contracted. This tension is one example of how flexing your muscles can help make them […]
What are disadvantages of DC?
What are disadvantages of DC? Disadvantages of DC Transmission: Due to commutation problem, electric power can’t be produced at High (DC) Voltage. In High Voltage transmission, we cant step-up the level of DC Voltage (As Transformer won’t work on DC). There is a limitation of DC switches and circuit breakers (and they are costly too). […]
