Degree-heating weeks-help with formulas

Hello, To understand how much heat stress corals are exposed to, we calculate what is known as a "degree-heating week:" this is the amount of time a temperature is above a known threshold (typically the mean monthly maximum or the bleaching threshold). Basically, I need to integrate the amount of time that the temperature has surpassed 31C in my dataset (attached). Temperature was measured four...

What are the pairs in the “each pair student’s t-test”?

I have analyzed 14 samples (named sample 1-sample 14) with 2 different methods (named method 1 and method 2).I want to see whether there is a difference between method 1 and method 2.The result of the measurement is concentration in ppm. The different samples have contents between 65 and 1200 ppm.I analyzed each sample 2-3 times with method 1 and 3 times with method 2.The leverage plot shows that ...

Sample size, confounding, bias

I have doubts. I use data on electricity consumption per capita (per year) from 1960-2014. The sample size in this case is N = 55 for the whole world, as well as for individual regions and countries. However, the annual per capita consumption of electricity for the world covers approximately 7,000,000,000 people, and for Norway, for example, about 5 million, but in both cases for the period from 1...

Models with weight

Hi I'm trying to find a correlation between some X predictors and a continuous response variable strongly skewed on the right. The database contains 140 instances only. First of all I transformed the response variable by using the function lnx+1. Then I normalized all the x in the range 0 and 1, reduced the dimensionality with the screening option and then removed the correlated predictors X. At t...

How can I make this polar plot in JMP?

I have a dataset including wind speed and direction. I would like to show the average wind speed in different wind direction with equal intervals (see attached). I have already binned the wind direction data into equal intervals. I also converted the wind speed and wind direction to components 'u' and 'v' using u = ws * cos(θ) and v = ws * sin(θ). I only need help in making a plot similar to the a...

XPath Query() and XML namespaces

I have a bunch of XML documents that I want to put into a data column. I want to use XPath expressions to pull out values from them, by appending columns that contain formulas that make use of the XPath Query() function. Some of my documents have XML-namespace qualified element names. For example, one might look like this: <?xml version="1.0" encoding="UTF-8"?> <synopsis xmlns="http://www.cap.org/...

Using JMP to Calculate Surface Flatness

Has anyone used JMP to calculate the Minimum Zone surface flatness of a point cloud? I have some differences between two metrology areas for our surface flatness requirements and wanted to check them in JMP. There are different algorithms for doing the calculation. (There is an ASME standard for the general rule, ASME Y14.5: " a tolerance zone defined by two parallel planes within which the surfa...

[JSL Contour Plot] Method of define contour plot, number, minimum, maximum

The contour plot is very helpful to show 3D map, however the problem of defining the zone is always a trouble. In my typical jsl plot, I use something below to define the contour plot zone number = 8, maximum = 1.4, minimum =1. However, the table column :Length may change time to time, and the scale will have to be modified manually for each corresponding plot. Does someone have experience how t...

Impact of screen resolution on html output

Hi, I'm preparing a dashboard using jmp that will be used for a daily meeting. It contains information in form of data tables and text boxes. In order to transfer text sizes and colors for the text as well as the data tables into the html output I transformed them into pictures (rep = dt << get as report(); pic = rep << get picture(); ). I set up all font sizes on my external monitor and it worked...
