Is there a 0%?5 answersYes, there is a mention of achieving a 0% goal in one of the contexts. The context by Amitai Etzioni discusses the "zero strategy" for nuclear disarmament, aiming for zero nuclear weapons globally. The strategy proposed by the Quad suggests reducing the number of warheads and extending treaties to achieve this goal. However, the author argues that this approach is dangerous, distracting, and unlikely to succeed in convincing nations to give up nuclear arms. This highlights the existence of a 0% goal in the context of nuclear disarmament discussions.
What is percentage in reaserch?5 answersPercentage in research refers to the proportion or rate of a specific variable within a study. In the contexts provided, percentages are utilized to quantify various outcomes. For instance, the instability of methane production in batch studies varied from 14.84% to 78.21%. In another study, the wave-absorbing properties of cement mortar were enhanced by 4% steel fiber, resulting in a maximum absorption of 8.5-16.5dB. Additionally, the purity of stevioside obtained after purification was reported at 98.7%. Furthermore, the elimination abilities of submerged macrophytes for cadmium ranged from 66% to 95%. These percentages play a crucial role in quantifying results and assessing the effectiveness of various processes and materials in research studies.
What is percentage in research with author?4 answersThe percentage system in research with authors refers to a special form of contributions where taxpayers can allocate a certain percentage of their personal income to support nonprofit organizations. This system was explored in an experimental research project to determine its impact on altruistic behavior and whether it led to a crowding out effect. The study found that the introduction of the percentage system did not significantly lower the level of individual contributions from income and even showed a slight increase in the first round of the experiment's second part. Additionally, the research revealed interesting differences in behavior between men and women in response to the new situation. The percentage system is one of the factors that contribute to the overall evaluation of author contributions in scientific research.
What is mean percentage error?5 answersThe mean absolute percentage error (MAPE) is a widely used measure of forecast accuracy. It is a scale-independent and interpretable measure. However, MAPE has a disadvantage of producing infinite or undefined values for zero or close-to-zero actual values. To address this issue, a new measure called the mean arctangent absolute percentage error (MAAPE) has been proposed. MAAPE is a slope as an angle, while MAPE is a slope as a ratio. MAAPE overcomes the problem of division by zero by using bounded influences for outliers. The theoretical properties of MAAPE have been investigated, and its practical advantages have been demonstrated using simulated and real-life data.
What is a good Mean Absolute percentage error?5 answersA good Mean Absolute Percentage Error (MAPE) is one that is not biased and can handle zero or close-to-zero actual values. The MAPE is widely used in businesses and organizations to measure forecast accuracy, but it has the disadvantage of producing infinite or undefined values for small actual values. To address this issue, a new measure called the Mean Arctangent Absolute Percentage Error (MAAPE) has been proposed. MAAPE overcomes the problem of division by zero by using bounded influences for outliers and preserves the philosophy of MAPE. It is important to note that MAPE systematically favors methods that under-forecast, making it biased when used for model selection. Therefore, an alternative relative error measure based on the forecast to actual ratio is recommended for model selection and estimation of prediction models.
What is required for high shooting percentages in basketball?5 answersTo achieve high shooting percentages in basketball, several factors are important. The shooting angle has a significant influence on the goal percentage, with a larger angle of incidence leading to higher shooting percentages. Additionally, the shooting velocity plays a role, with a higher velocity allowing for a greater allowable deviation in shooting angle. The height of the shooting also affects the goal percentage, with a shooting height between 1.8-2.1m requiring a shooting velocity higher than 8m/s. Furthermore, the arc of the basketball flight is crucial, as a higher arc leads to a higher hit rate in shooting. Finally, proper shooting technique and fundamental training programs have been shown to increase shooting percentages.
