统计分析 Jobs

Statistical analysis is a mathematical science, the practice of evaluating and understanding quantitative data. Statistical analysis will make sense of indexes such as standard deviation, and note outliers. The analysis of the data may aid in decision-making in the face of uncertainty.

Quantitative data is represented as numbers, and therefore may be presented in graph format. This simplifies the explanations and visualizations of the data’s meaning. The graph alone will show a positive or negative correlation, a bell curve, or no correlation at all.

Statistics require a population to be studied, and statistical analysis is commonly used regarding census data organized by governments, sociology and medicine.

    Hi, I need summary output in Excel for the given problem and interpretations for the below 6 questions: Problem Statement: A digital media company (similar to Voot, Hotstar, Netflix, etc.) had launched a show. Initially, the show got a good response, but then witnessed a decline in viewership. The company wants to figure out what went wrong. Approach: We are concerned about determining the driver variable for show viewership. This is the case of pridiction rather than projection where we are more interested in predicting the key driver variables and their impact rather than forecasting the results. First we will list down the potential reasons for the decline in viewership. The potential reasons could be: Questions: 1. Decline in the number of people coming to the platform 2. Fewer...

    A web-based map using .net6 core MVC to visualize the sensors already exists. So, To increase information density, you may want to think about what else you want to visualize. A preview of the current and historical sensor. You could embed some plots in the map or design some glyphs. Further, as this is a web-based prototype and not some static map, you may want to think about interactivity a bit more. What can the user adjust in your solution interactively? adding interactive filters based on sensor type or a time slider for the historical sensor data. about interactively comparing data from multiple selected sensors Bottom line: Think where your solution is better or at least as good as existing previous work. Check with the domain users what are their needs in terms of the sensor data...

    IN R programming (a) Pre-processing: Check the data to see if there is any missing value. The simplest approach to deal with the missing values is to remove the rows with any missing values. Use are free to pick other methods from literature to deal with missing data. Remember that the final data provided to the regression models should not have any missing value. Also, make sure that the variables have the correct type. For example, “station” number doesn’t really have a numerical meaning! Or the date should not be included as a predictor. (b) Split the data into three parts. Based on the “date”, consider the first 60% for training (Train), the next 20% for validation (Valid), and the last 20% for testing (Test). We will not touch the test set until the very ...

    Let’s say you have 8 teams of 4 people making widgets. Each “batch” of widgets is produced every two weeks like clockwork. Each widget is unique enough so the team estimates with a number. Higher the number the greater the complexity. So the most obvious measurement over time is the average correct? 80 widgets produced over 2 months is 4 batches , so 20. Managers notice that this is not a predictable way to forecast though. Each batch produced might be as low as 2 or a high 30. So accuracy forecasting any given batch is not valuable. The historical data goes back years and years. To the naked eye you can also see production dips in Nov and Dec, but generally increases during march and May. Other data points available.

    I seek to test if there exists any relationship between health expenditure and the growth rate of an economy. The chosen country is Germany and the time period of this study is 1980 to 2021. The Independent variable is GDP per capita and the dependent variable is health expenditure per capita. The log of both variables is taken for further analysis. As it is a time series data, a Basic stationary test of ADF is employed. It is followed by a bound cointegration to find if there is a long-term relationship between the two variables. As there is none, the ARDL model is employed. Tests of robustness and stability are too performed. As it is an independent project and my first time using Stata, I am struggling with interpretation as well as doubting the models if they are the right way to appr...

In order to practice these skills, this mini-project requires you to first develop and interpret point and interval estimates for each variable’s population mean (or proportion in the case of a nominal variable) individually. Secondly, this mini-project focuses on creating and evaluating a hypothesis test on the population mean or proportion. Make sure that over the course of this assignment you demonstrate the ability to do both one-tailed and two- tailed hypothesis tests. Your responses must be type-written in 12-point font and double spaced. Remember to include all relevant Excel output in the Microsoft Word document.
