This dataset, histamine_matrix, is a matrix containing data on blood histamine levels in dogs after drug treatment. Sixteen dogs were used to assess morphine and trimethaphan effects on blood histamine concentration. Dogs were divided into four groups: two received morphine, two received trimethaphan (both intravenous). In each drug pair, one group had histamine depleted prior to treatment, the other retained normal levels. Values of "0.10" indicate originally missing data, arbitrarily imputed with that value.
