FindFormula

FindFormula[data] finds a pure function that approximates data.

• FindFormula[data,x] finds a symbolic function of the variable x that approximates data.
• FindFormula[data,x,n] finds up to n functions that approximate data.
• FindFormula[data,x,n,prop] returns up to n best functions associated with property prop.
• FindFormula[data,x,n,{prop1,prop2,…}] returns up to n best functions associated with properties prop1, prop2, etc.

Examples

(* Find a formula from data *)
data = Table[{x, x^2 + 2x}, {x, 0, 5}];
FindFormula[data, x]

(* Find multiple candidate formulas *)
FindFormula[data, x, 3]

(* Get specific properties *)
FindFormula[data, x, 1, "BIC"]
