• Unable to fit a 4PL curve after applying weighting (1/y^2)

  I am attempting to analyze a data set that utilizes raw signal points (y, response) and concentration (x, predictor formula) for an ELISA type assay using a logistic 4P model on the data. Once I apply a 1/y^2 weighting to the raw signal points column, the graph can no longer fit giving an R = ~0.45. This same plate has been analyzed with another software okay, so I am wondering what is happening h...

• graph builder, local data filter, and large data sets

  Hello,  I have a dashboard of sorts using local data filter and graph builder to browse through a stacked dataset of measurement data (one VALUE column and a few measurement identifier columns. The functionality is great, but if my dataset is large, JMP freezes/crashes as it tries to jam all the data into the initial, unfiltered graph when the graph builder script is launched or the local data fil...
