So I decided to create my own JS library that:. Not a JS developer? Just want to play with the library? Please keep in mind that this library is still in its infancy. And of course let me know if you notice any issues. To be involved you have to be willing to make a large commitment in terms of time or money I plan to contribute both. I have a set of proposed guidelines for identifying potential arbitrage targets, send me an email for more info. Also, this would not necessarily be targeted at horse racing. If you are a first-timer here at StatisticsBlog.
Secondly, it was already split into two groups, and the two groups by the way have absolutely zero scientific basis. Shown at top, above the quote by Konnikova, is a simulation of the study in question , under the assumption that the results were completely random the null hypothesis. The actual group of interest had just 48 women. Of those, 34 correctly guessed the sex of their gestating babies. In general, the larger your sample size, the more power you have.taylor.evolt.org/lonyx-ligar-chicas-belmonte.php

Adding together the two green areas in the tails, their study has a p-value of about 0. This a full order of magnitude beyond the generally used threshold for statistical significance. Their study found strong evidence that women can guess the sex of their babies-to-be. Is this finding really as strong as it seems? Perhaps the authors made some mistake in how they setup the experiment, or in how they analyzed the results. Since apparently Konnikova failed not only to do statistical analysis, but also basic journalism, I decided to clean up on that front as well.
I strongly recommend [Dr. Mahometa] and this class! So far this course has fully met my expectations, it is very well done, very interesting and tutorials are terrific.

The reading part is also well done and contains numerous examples to train oneself. We will cover basic Inferential Statistics — integrating ideas of Part 1.
If you have a basic knowledge of Descriptive Statistics, this course is for you. We will learn how to sample data, examine both quantitative and categorical data with statistical techniques such as t-tests, chi-square, ANOVA, and Regression. I took Prof.
From Basic to Advanced Applied Statistics using R
This I think can be taken individually but might have a steeper learning curve. The course is designed beautifully with pre-labs, labs and assignments that cement the concepts learned through text and videos. I have been around on edX since it started and I must say it is hard to find such well-designed course and that too [are offered] for free. I hope Prof. Mahometa design more courses on advanced topics. It will be a treat to learn. I took part 1 and enjoyed it a lot, so it was very easy to decide to go on with part 2. Mahometa and team are very good teachers and their material is of a very high quality.
The exercises are interesting and the materials videos, labs and problems are appropriate and well chosen. I recommend this course to anyone interested in statistical analysis as an introduction to machine learning, big data, data science, etc. On a scale from 1 to 10, I give 50! The specialization is taught by the same professor, plus a few additional faculty members. The early reviews on the new individual courses, which have a 3. The syllabi are comprehensive and have full sections dedicated to probability. Prominent reviews follow. Estimated timeline : Each course has an estimated timeline of weeks at hours per week.
In this Specialization, you will learn to analyze and visualize data in R and created reproducible data analysis reports, demonstrate a conceptual understanding of the unified nature of statistical inference, perform frequentist and Bayesian statistical inference and modeling to understand natural phenomena and make data-based decisions, communicate statistical results correctly, effectively, and in context without relying on statistical jargon, critique data-based claims and evaluated data-based decisions, and wrangle and visualize data with R packages for data analysis.
You will produce a portfolio of data analysis projects from the Specialization that demonstrates mastery of statistical data analysis from exploratory analysis to inference to modeling, suitable for applying for statistical analysis or data scientist positions. You will examine various types of sampling methods, and discuss how such methods can impact the scope of inference. A variety of exploratory data analysis techniques will be covered, including numeric summary statistics and basic data visualization. You will be guided through installing and using R and RStudio free statistical software , and will use this software for lab exercises and a final project.
The concepts and techniques in this course will serve as building blocks for the inference and modeling courses in the Specialization. This course covers commonly used statistical inference methods for numerical and categorical data. You will learn how to set up and perform hypothesis tests, interpret p-values, and report the results of your analysis in a way that is interpretable for clients or the public. Using numerous data examples, you will learn to report estimates of quantities in a way that expresses the uncertainty of the quantity of interest.
The course introduces practical tools for performing data analysis and explores the fundamental concepts necessary to interpret and report results for both categorical and numerical data. This course introduces simple and multiple linear regression models. These models allow you to assess the relationship between variables in a data set and a continuous response variable. Is there a relationship between the physical attractiveness of a professor and their student evaluation scores? Can we predict the test score for a child based on certain characteristics of his or her mother?
In this course, you will learn the fundamental theory behind linear regression and, through data examples, learn to fit, examine, and utilize regression models to examine relationships between multiple variables, using the free statistical software R and RStudio. The course will apply Bayesian methods to several practical problems, to show end-to-end Bayesian analyses that move from framing the question to building models to eliciting prior probabilities to implementing in R free statistical software the final posterior distribution.
Additionally, the course will introduce credible regions, Bayesian comparisons of means and proportions, Bayesian regression and inference using multiple models, and discussion of Bayesian prediction. A large and complex dataset will be provided to learners and the analysis will require the application of a variety of methods and techniques introduced in the previous courses, including exploratory data analysis through data visualization and numerical summaries, statistical inference, and modeling as well as interpretations of these results in the context of the data and the research question.
The analysis will implement both frequentist and Bayesian techniques and discuss in context of the data how these two approaches are similar and different, and what these differences mean for conclusions that can be drawn from the data. A sampling of the best final projects will be featured on the Duke Statistical Science department website. Note: Only learners who have passed the four previous courses in the specialization are eligible to take the Capstone. The slides are beautiful and visually appealing, making following the rigorous content easier to digest.
Instructors are captivating and articulate, the explanations are clear and concise. The assignments are very very tough, making the course incredibly challenging, but worth it.
