Repeated Measures ANOVA: missing data(?)
I have a dataset consisting performance (D) for participants that each did 3 frequencies on 3 image types. There are 5 total possible frequencies, so there is always 2 frequencies a participant did not see (missing data). However, all of them saw the baseline F0, which means I could potentially subtract the F0 baseline from the other performances to get change in performance.
My dataset has the following structure:
Frequency: 5 levels, ordinal - could potentially be used as a continuous predictor?
Imagetype: 3 levels
ID: within-subject design, random factor
I am trying to perform a Repeated Measures ANOVA, but this is indicating 'Error while loading data, please verify your repeated measures observations'.
Is this because of the missing data or something else? Is it even possible to run a repeated measures ANOVA here? For example, is there a way to deal with the missing data?
Alternatively, what other way would you recommend to analyse this data using Bayesian statistics?
Thank you for any help - I have been reading up on statistics & bayesian statistics in the last weeks and would love to hear your insights
