![]() ![]() This is what model selection allows and it is becoming increasingly used in ecology and evolutionary biology. This is an inferential or frequentist approach to statistics.Īn alternative approach is to simultaneously test multiple competing hypotheses, with each hypothesis being represented in a separate model. This low probability then allows us to reject the null hypothesis in favour of the more biologically interesting alternative hypothesis. t-statistic, F-value, etc.), and rejected the null hypothesis when the observed test statistic falls outside the test statistic distribution with some arbitrarily low probability (e.g. Up to now, when faced with a biological question, we have formulated a null hypothesis, generated a model to test the null hypothesis, summarized the model to get the value of the test-statistic (e.g. 01: Linear models and statistical modelling 19: Data wrangling in dplyr, ggplot, tidy data 10: Intro to course, programming, RStudio, and R Markdown ![]()
