## What is TOPSIS

**T**echnique for **O**rder **P**reference by **S**imilarity to **I**deal
**S**olution (TOPSIS) originated in the 1980s as a multi-criteria decision
making method. TOPSIS chooses the alternative of shortest Euclidean distance
from the ideal solution, and greatest distance from the negative-ideal
solution. More details at [wikipedia](https://en.wikipedia.org/wiki/TOPSIS).

<br>

## How to use this package:

TOPSIS-GIRIK-GARG-102003178  can be run as in the following example:


### In Command Prompt to run the code:
```
topsis data.csv "1,1,1,1" "+,+,-,+" out.csv
```
<br>

## Sample dataset

The decision matrix (`a`) should be constructed with each row representing a Model alternative, and each column representing a criterion like Fund Name , P1 ,P2 , P3 , P4 , P5.

Model | Correlation | R<sup>2</sup> | RMSE | Accuracy
------------ | ------------- | ------------ | ------------- | ------------
M1|	0.8	|0.64	|3.5	|37.5	|10.61
M2|	0.86	|0.74	|3.4	|42.2	|11.8
M3|	0.69	|0.48	|5.7	|70	|19.22
M4|	0.65	|0.42	|5.7	|65.5	|18.07
M5|	0.9	|0.81	|6.6	|39.1	|11.85
M6|	0.76	|0.58	|4	|53.5	|14.71
