![]() ![]() How many interactions does a 3 way ANOVA have? Can you do a 3 way ANOVA in Excel?Įxcel doesn’t have a three-factor ANOVA data analysis tool, and so we will need to carry out the analysis using Excel formulas. ![]() write_csv(data, 'data.The three-way ANOVA is used to determine if there is an interaction effect between three independent variables on a continuous dependent variable (i.e., if a three-way interaction exists). Use map functions to run it on list of models. You can extract the relevant statistics from the summary or store the model in a list and use broom::tidy on it to get all the stats together in a dataframe. Results <- lapply(formulae, function(x) summary(aov(x, data = df1))) ![]() library(titanic)įilter(Embarked != "") # deleting empty Embarked statusįormulae <- lapply(colnames(df1), function(x) as.formula(paste0(x, " ~ Sex * Embarked"))) I'm open to suggestions on how to output this - just want to be able to easily identify what values are significant, ideally with each dependent variable on its own line. In this case I've set Sex & Embarked as my categorical variables, and would like the output for the effects of Sex Embarked and ~ Interaction somehow saved to a file. I've made an example using the titanic dataset. ![]() Ideally, I'd like it to have this in a format where each of my several hundred dependent variables is in it's own row, with the pVaules and Fvalues I've figured out how to run a 2-way anova on several variables in my data frame, but not sure how to get this into a format that could be easily exported to a csv file or excel. ![]()
