An easy to use csv data analyser.
The csv-analysis tool’s goal is to provide an easy way to analyse your data with different tools so you can then create a customized tool that matches your data’s needs.
In the case of a single column analysis, it will provide statistical information on the data.
In the case of X, Y datasets, it will provide different plots with the following:
-
Y vs X.
-
Y vs X, least squares polynomial regression.
-
Linear Transformation Y vs X, least squares linear regression.
In the case of X, Y datasets, where the X dataset is time based, it will plot Y vs X and provide statistical information on the Y data.
| Type | Equation | Linear | Transformation |
|---|---|---|---|
Power |
\$y = ax^b\$ |
\$log y = log a + b * log x\$ |
\$Y = log y\$ |
Exponential |
\$y = ae^(bx) = aB^x\$ |
\$ln y = ln a + bx = ln a + ln B * x\$ |
\$Y = ln y\$ |
Logarithmic |
\$y = a + b ln x\$ |
\$y = a + b ln x\$ |
\$Y = y\$ |
Reciprocal |
\$y = a + b / (1 + x)\$ |
\$y = a + b * 1 / (1 + x)\$ |
|
Reciprocal |
\$y = 1 / (a + bx)\$ |
\$1/y = a + bx\$ |
|
Reciprocal |
\$y = 1 / (a + bx)^2\$ |
\$1/sqrt(y) = a + bx\$ |
|
Square Root |
\$y = a + b * sqrt(x)\$ |
\$y = a + b * sqrt(x)\$ |
-
Clean up code.
-
Add a nicer Readme.
-
Add man page.
-
Split into cli app and lib to allow for custom solutions.
-
Add list of common date formats to ease --xtimeformat use.
-
Read date formats in non-golang date formats. For example, the
datecommand format. -
Fix R2 calculations.
-
Change power transformation from Log10 to Ln.
-
Add Growth \$y = ae^(b/x)\$ → \$ln y = ln a + b * 1/x\$
-
Add hyperbola \$y = x / (ax - b)\$ → \$1/y = a - b (1/x)\$
