Most statistical procedures benefit from understanding the underlying population distribution, or at the very least offering reassurance that our assumptions about those distributions are valid. JMP provides a number of ways to easily explore and investigate distributional assumptions. In this post, I provide information on fitting continuous or discrete distributions
Bootstrapping is a popular resampling method for estimating the sampling distribution of a statistic. While the theory behind resampling methods dates back to Sir R.A. Fisher, bootstrap resampling was first proposed by Bradley Efron in the 1970s. Bootstrapping involves repeatedly sampling from a data set, with replacement, in order to
Note: This blog post is contributed by Alex Spancake, who was the JMP Academic Team's summer intern. Mia Stephens worked with Alex on this project. During my summer internship with the JMP Academic Team, I developed a number of textbook add-ins, which package data sets and other teaching resources into
As part of the International Year of Statistics, this month we celebrate the American statistician, consultant, author and a founding father of quality management, Dr. W. Edwards Deming. If you’ve taken a course in quality management, continuous improvement or industrial statistics, you’ve no doubt been introduced to Deming and his
The 2013 Intel International Science and Engineering Fair (ISEF), which was held in Phoenix, Arizona, concluded May 17. This year, approximately 1,600 high school students from more than 70 countries and territories competed for more than $4 million in prizes. The winners were recently announced. Congratulations to the winners of
From May 12-17, 2013, more than 1,500 high school students from over 70 countries will compete in the annual Intel International Science and Engineering Fair (ISEF) in Phoenix, Arizona. The world's largest pre-college science and engineering competition, the fair hosts the brightest and most talented young researchers in science, engineering
Have you ever been in this situation? You’re teaching a class using JMP, and you’d like all of your students to have the same Preferences. For example, you’d like everyone to have large markers and horizontal histograms. Or, perhaps you’d like certain statistics or graphical features to display each time you run an
At the recent JMP Discovery Summit, I overheard a conversation between a professor and one of the JMP developers, Clay Barker. The professor was interested in understanding tools available for generating distributions in JMP. My first thought (although I was just a fly on the wall) was to suggest the
One of the great new pleasures in life, if you enjoy crunchy chocolate, is pretzel M&Ms. If you haven’t tried then yet, you should! I’m down to my last five – one of each color (red, blue, brown, green and orange.) Should I eat just a couple and save the
Have you checked out the JMP Learning Library lately? Designed for students in introductory statistics courses – or anyone new to JMP – the Learning Library provides short guides, tutorials and links to other resources for getting started with JMP. Now, we all know that JMP is easy to use.
