If the data don’t resemble what you’d “expect” to see if the null hypothesis were true, then it probably isn’t true. Okay, if the null hypothesis were true, what would we expect to see?
WebJan 20, 2024 · Normally, a goodness-of-fit test presumes a comparison between empirical data and theoretical data... in other words, between the real observations and the values produced by a function that approximates them. Since you are working with curves, the fit function already provides all what you need in order to perform the test: WebMar 26, 2024 · The Akaike information criterion (AIC) is a mathematical method for evaluating how well a model fits the data it was generated from. In statistics, AIC is used …
The following conditions are necessary if you want to perform a chi-square goodness of fit test: 1. You want to test a hypothesis about the distribution of one categorical variable. If your variable is continuous, you can convert it to a categorical variable by separating the observations into intervals. This process is known … See more A chi-square (Χ2) goodness of fit test is a goodness of fit test for a categorical variable.
