Expiration and retest intervals are commonly assigned to pharmaceuticals as well as a wide range of other products. These dates are often extrapolated from a limited set of stability data using statistical models that regress the stability trend to some point in the future. A confidence interval around the regression…
This blog post details a process for making figures in JMP that can be used in PowerPoint in such a way that every time the PowerPoint file is opened it pulls the current version of the figure that JMP makes into the current slide deck. This might sound like a fancy new feature, but the option to insert and link a picture…
Ever since scientists started using ANOVA, the result have been represented with a bar chart for each treatment, and one-sided wisker above the plot to represent the 95% confidence interval*. This makes comparing the treatment groups easy. If the next bar is higher/lower than the wisker then its significantly different…
Fishbone Diagrams Fishbone diagrams are a fantastic tool for communicating cause and effect relationships graphically. Essentially, they are a hierarchical diagram for showing the relationships between inputs to a process and some key output. This type of information could be presented in an index like table, but really,…
It's not Normal, or is it? In several recent discussions about using parametric tests the question of whether the data is normally distributed (or passes a goodness of fit test for normality) has come up. In each of the cases the sample size was relatively low (<30) and the conclusion was that the data did not come from a…
Graph builder can display value labels on bar graphs, unfortunately, if data is also plotted on the bar graph, the labels are completely obscured. Fortunately it is relatively easy to manually reposition the labels. Getting alignment correct is a wee bit tricky, and doing this more than once is relatively frustrating. Even…
I run into a problem where I want to see what my old control limits would look like relative to the current or new fixed control limits for a set of control charts. Typically, I'd go about adding reference lines to each graph, but I think there might be a better way, using a long forgotten (at least to me) platform…
This is the journal and presentation materials for Session 4 of the Pharma and Biotech Data Discovery Series, Summer 2020 The topic of this session is: Chemistry Manufacturing and Controls (CMC) Statistics The Journal can be downloaded from the link below, and was prepared By Alisa Hunt-Lowery, JMP Systems Engineer for…
This journal provides background for thinking about DOE design and analysis. A key component is the DOE Walkthrough. It is a step-by-step guide for setting up your first DOE. Its very similar to the tutorial under the HELP>Tutorials>DOE Tutorial option in JMP, but with a couple of helpful short-cuts and a pharma flavor.
Multiple Y-Axis with a Scaled Response Overlay Graph STOP! If you just want the script, it is attached at the bottom of the post. EDIT: Stop! - This is now implemented in Graph Builder for v19. : ) This is a specialized graph that scales all of the y-axis variables and overlays them and then provides the y-axis scale in…
