Dear List members, When attempting to run Amelia on a .csv file I receive the following error: There was an unexpected error in the execution of Amelia. Double check all inputs for errors and take note of the error message: Error in colSums(sapply(priors[, 1, drop = FALSE], ">", blanks)) : 'x' must be an array of at least two dimensions I have no idea what this means and as an AMELIA novice I would appreciate any help anyone can give! Many thanks, Ian Ian Moran Assistant Psychologist Child and Adolescent Psychology 2nd Floor, 'A' Block St Leonard's Nuttall St London N1 5LZ Direct: 020 7683 4311 Switch: 020 7683 4000 ********************************************************************* City and Hackney Teaching Primary Care Trust does not accept any responsibility for the content of this e-mail nor for any consequence of its use and storage.
