Exploratory Factor Analsys - on the base of TIMSS2015 data
Note!
Comment received from a teacher was as follows:
EDA: the describe function is only suitable for interval variables
hetcor should be done before converting variables to numeric, so it just counts the same Pearson correlations
fa: you should either use cormatrix or argument cor="mixed". You cannot simply run fa on your dataframe
Not a very accurate interpretation of interaction in regression
And avoid using causal language such as influence, depend, etc.
Interactive plots with highcharter
Highcharter allows for nice visualizations. Example with gapminder data.
