ResourceFunction["CurveFitOverview"][data,var,type]

performs a numeric fit of the specified type to data with respect to the user-specified variable x and returns an Association of the result.

Details and Options

type can be "Linear", "Quadratic", "Cubic", "Quartic", "Quintic", "Logit", "Probit", "Exponential", "Log", "Power" or {"Polynomial",power} for a given integer power.

Examples

Basic Examples (3) 

Compute information about a power fit to a given set of data:

In[1]:=
ResourceFunction[ "CurveFitOverview", ResourceSystemBase -> "https://www.wolframcloud.com/obj/resourcesystem/api/1.0"][{{1, 2}, {3, 4}, {5, 6}}, x, "Power"]
Out[1]=

Compute information about a second-degree polynomial fit to a given set of data:

In[2]:=
ResourceFunction[ "CurveFitOverview", ResourceSystemBase -> "https://www.wolframcloud.com/obj/resourcesystem/api/1.0"][{{1, 2}, {3, 6}, {5, 9}, {7, 11}}, x, {"Polynomial", 2}]
Out[2]=

Compute information about an exponential fit to a given set of data:

In[3]:=
ResourceFunction[ "CurveFitOverview", ResourceSystemBase -> "https://www.wolframcloud.com/obj/resourcesystem/api/1.0"][{{1, 2}, {3, 6}, {5, 9}, {7, 11}}, x, "Exponential"]
Out[3]=

Properties and Relations (1) 

The information returned by CurveFitOverview can be visualized as a report using the resource function CurveFitReport:

In[4]:=
ResourceFunction[ "CurveFitReport"][{{1, 2}, {3, 6}, {5, 9}, {7, 11}}, x, "Exponential"]
Out[4]=

Possible Issues (1) 

CurveFitOverview will return unevaluated if the specified data is not compatible with the given type:

In[5]:=
ResourceFunction[ "CurveFitOverview", ResourceSystemBase -> "https://www.wolframcloud.com/obj/resourcesystem/api/1.0"][{{1, .2}, {3, .4}, {5, 5}}, x, "Logit"]
Out[5]=
