returns the range of values within one standard deviation of the mean for all properties of human growth at the specification spec.
returns the range of values within one standard deviation of the mean of a property for the specification spec.
returns the values for all properties of human growth for spec at the specified percentile.
returns the value at a specific index of a property for spec at the specified percentile.
returns the percentile and probability density for a specific value quantity of the property at spec.
Details 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 "Male" or "Female". It can also be the appropriate gender Entity.
- If gender is not specified, then an Association with results for both "Male" and "Female" 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 "Milestones" typical developmental milestones reached around this age "NextMilestones" next milestones to expect "PreviousMilestones" milestones immediately proceeding this age "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 "Percentage" or "ZScore". "ZScore" 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:
Method Automatic determine model used UnitSystem $UnitSystem return units of the desired unit system
- Method contains the suboption "Model", which allows you to specify the model to use. Available models include "CDC" and "WHO".
- The "CDC" model uses data from the Centers for Disease Control and Prevention, http://www.cdc.gov/growthcharts. The "WHO" model uses data from the WHO Multicentre Growth Reference Study Group.
