HumanGrowthData

HumanGrowthData[spec]
returns the range of values within one standard deviation of the mean for all properties of human growth at the specification spec.

HumanGrowthData[spec,property]
returns the range of values within one standard deviation of the mean of a property for the specification spec.

HumanGrowthData[spec,index]
returns the values for all properties of human growth for spec at the specified percentile.

HumanGrowthData[spec,property,index]
returns the value at a specific index of a property for spec at the specified percentile.

HumanGrowthData[spec,property,quantity]
returns the percentile and probability density for a specific value quantity of the property at spec.

Details and OptionsDetails and Options

  • The specification spec is an Association of the form Association["Age"->age,"Gender"->gender].
  • Age can be given as a positive Quantity of time or as a birth date using DateObject.
  • Data is not available for all ages. Human growth data is not available over the age of 20 years old.
  • Gender can be given as or . It can also be the appropriate gender Entity.
  • If gender is not specified, then an Association with results for both and is returned.
  • Available properties include:
  • "BMI"body mass index
    "HeadCircumference"widest circumference of the head
    "Height"length as measured standing
    "Length"length as measured lying down
    "Weight"weight
  • The percentile index can be used to obtain the values of a property for a specified percentile in the distribution of a person with the specified gender and age.
  • The percentile index can be either a percentage Quantity between 0 and 100 percent or a number between 0 and 1, both exclusive. It can also be specified as an Association with the key or . allows the value at a specific z-score, or number of standard deviations, from the mean (at 0). Z-score should be specified as a number between and .
  • If no index is specified for an indexed property, the interval within a standard deviation of the mean is returned.
  • When a property is not specified, values for all properties will be returned as an Association with the properties as keys.
  • quantity should be a Quantity object and have compatible units for the property in question.
  • HumanGrowthData[spec,property,"StandardDeviation"] returns the StandardDeviation for that specification and property combination.
  • HumanGrowthData[spec,property,"Distribution"] returns a distribution for the specification and property combination, either a LogNormalDistribution for weight or a NormalDistribution.
  • HumanGrowthData takes the options:
  • MethodAutomaticdetermine model used
    UnitSystem$UnitSystemreturn units of the desired unit system
  • Method contains the suboption , which allows you to specify the model to use. Available models include and .
  • The model uses data from the Centers for Disease Control and Prevention, http://www.cdc.gov/growthcharts. The model uses data from the WHO Multicentre Growth Reference Study Group.
