GraphPad Prism 9 Curve Fitting Guide Example Simple logistic regression
When a categorical variable is inserted in a regression model as a predictor, Prism automatism encodes this variable using "dummy coding". This process generates (behind the scenes) an number of new set equal at the number on floor of the original criteria variable minus one.

Odds = (Probability of success)/ (1 - Probability of success) For example, let's say there's a 75% probability of success, the odds would then be calculated as: Odds = 0.75/ (1 - 0.75) = 0.75/0.25 = 3 Commonly, we would say that "the odds are 3:1" (read "three to one").

[S] Help with logistic regression in GraphPad Prism 9 Hi everyone! I'm writing my doctorate at the moment and for one hypothesis I need to compare three groups and if a specific condition is present or not in these. So all the data is made up of 0/1 (yes/no) and I need to perform a logistic regression analysis in GraphPad.

The goal of logistic regression is to perform predictions or inference on the probability of observing a 0 or a 1 given a set of X values. In the following, we write the probability of Y = 1 as P (Y=1). Logistic regression fits a linear regression model to the log odds. The odds are defined mathematically as P (Y=1) / P (Y=0).

When a variable is categorical (survived/died, male/female, 1st/2nd/3rd class, etc.), we can encode those responses as a set of 0s and 1s in a process called dummy coding (there are other coding techniques, but dummy coding is probably the easiest to understand).

Analyzing radioimmunoassay (RIA) or an enzyme-linked immunosorbent assay (ELISA) data is a two-step process: Prepare and assay a set of "known" samples, i.e., samples that contain the substance of interest in amounts that you choose and which span the range of concentrations that you expect to be present in your "unknown" samples.

For example, setting the classification cutoff to 0.5 is common (and default for simple logistic regression in Prism), and means that if the model predicts a probability of success greater than or equal to 0.5, then that prediction is classified as a "success" (Y=1), while if the model predicts a probability less than 0.5, it will classify it as.
