imputed simulated failed

[fabien-tell]

Hello,
I try to use missCompare for imputation of a df with 100 individuals (cells here) and 27 variables.
1/ The pgm failed by saying that for Amelia II I need more individuals, or I should reduce the number of order for polynomials :

[1] "Amelia II imputation - in progress" You have a small number of observations, relative to the number, of variables in the imputation model. Consider removing some variables, or reducing the order of time polynomials to reduce the number of parameters. error: chol(): decomposition failed

2/I have to set min_PDM = 2, less than 10, otherwise it does not start
May I fix this ?
Thanks
