## Colic horse data set

### Description

This is a modified version of the original training data set taken from the UCI repository, see reference. The modifications are only related to having appropriate levels for factor variables. This data set is about horse diseases where the task is to determine, if the lesion of the horse was surgical or not.

### Format

A training data frame with 300 observations on the following 31 variables.

surgery

  yes or no

age

  1 equals an adult horse, 2 is a horse younger than 6 months

hospitalID

  ID

temp_rectal

  rectal temperature

pulse

  heart rate in beats per minute

respiratory_rate

  a normal rate is between 8 and 10

temp_extreme

  temperature of extremities

pulse_peripheral

  factor with four categories

capillayr_refill_time

  a clinical judgement. The longer the refill, the poorer the circulation. Possible values are 1 = < 3 seconds and 2 = >= 3 seconds

pain

  a subjective judgement of the horse's pain level

peristalsis

  an indication of the activity in the horse's gut. As the gut becomes more distended or the horse becomes more toxic, the activity decreases

abdominal_distension

  An animal with abdominal distension is likely to be painful and have reduced gut motility. A horse with severe abdominal distension is likely to require surgery just tio relieve the pressure

nasogastric_tube

  This refers to any gas coming out of the tube. A large gas cap in the stomach is likely to give the horse discomfort

nasogastric_reflux

  posible values are 1 = none, 2 = > 1 liter, 3 = < 1 liter. The greater amount of reflux, the more likelihood that there is some serious obstruction to the fluid passage from the rest of the intestine

nasogastric_reflux_PH

  scale is from 0 to 14 with 7 being neutral. Normal values are in the 3 to 4 range

rectal_examination

  Rectal examination. Absent feces probably indicates an obstruction

abdomen

  abdomen. possible values 1 = normal, 2 = other, 3 = firm feces in the large intestine, 4 = distended small intestine, 5 = distended large intestine

cell_volume

  packed cell volume. normal range is 30 to 50. The level rises as the circulation becomes compromised or as the animal becomes dehydrated.

protein

  total protein. Normal values lie in the 6-7.5 (gms/dL) range. The higher the value the greater the dehydration

abdominocentesis_appearance

  Abdominocentesis appearance. A needle is put in the horse's abdomen and fluid is obtained from the abdominal cavity

abdomcentesis_protein

  abdomcentesis total protein. The higher the level of protein the more likely it is to have a compromised gut. Values are in gms/dL

outcome

  What eventually happened to the horse?

surgical_lesion

  retrospectively, was the problem (lesion) surgical?

lesion_type1

  type of lesion

lesion_type2

  type of lesion

lesion_type3

  type of lesion

cp_data
temp_extreme_ordered

  temperature of extremities (ordered)

mucous_membranes_col

  mucous membranes. A subjective measurement of colour

mucous_membranes_group

  different recodings of mucous membrances
