Statistic functionalities
=========================

[](#statistic-functionalities)

**This repository is made for solutions involving software from NewCompliance B.V Group**

The functions included in this library will calculate deviation and correlation in from a JSON file.

The demo included will give you an example on how to make use of this library

Install the library
-------------------

[](#install-the-library)

Require the library in your composer.json

`composer require wesleyk079/statistic_functionalities "dev-master"`

Make sure your framework or php-script loads the 'autoload.php' from composer's vendor directory.

\#1 Deviation
-------------

[](#1-deviation)

**Include the library:**

Use 'statisticFunctionalities\\functions\\Deviation';

**Adjust the options as wanted**

```
//example for setting the options
$options = [
    "FileToCheck"               => json_decode(file_get_contents("../generatedFiles/generatedInformation.json")),
    "KeyToSelect"               => "Verrichting 1",
    "KeyToSearchFor"            => "Operatieduur",
    "RemoveOutliers"            => true,
    "SecondComparison"          => true,
    "SecondKeyToFindDeviation"  => "Geplande duur",
    "FirstCategoryMax"          => 20,
    "MiddleCategoryMax"         => 60,
    "FirstPercentageMeasure"    => 20,
    "MiddlePercentageMeasure"   => 12.5,
    "LastPercentageMeasure"     => 10,
    "PositiveFeedback"          => "Wel goed in te schatten",
    "NegativeFeedback"          => "Niet goed in te schatten"

];

```

**Initialize the deviation class**

```
$deviation = new statisticFunctions\Deviation($options);

```

**Get the results**

```
$deviationResults = $deviation->GetDeviationStatistics();

```

What does my result contain?
----------------------------

[](#what-does-my-result-contain)

The following keys will be available from all results in the returned array

**amount** - the amount of measured cases

**mean** - the mean of all meaasured numbers

**standardDev** - standard deviation (1 time)

**statisticMin** - mean - (standarddeviation \* 3)

**statisticMax** - mean + (standarddeviation \* 3)

**lowerThanComparison** - Amount of cases where the number lower than the comparison number

**higherThanComparison** - Amount of cases where the number was higher than the comparison number

**Advice** - Advice as stated at the settings (positive or negative feedback). If (standarddeviation \* 3) is smaller than (mean \* percentage), it will be positive. The percentage will be taken from the percentageMeasure based on categories.

### Example on how to treat the results

[](#example-on-how-to-treat-the-results)

```
foreach($deviationResults as $result){

    There were  cases that included '' as .

    The data was divided by a standard deviation of ' ~ '

    This means in 68.26% of the cases,  will be
    between
}

```

\#2 Correlation
---------------

[](#2-correlation)

Change options to your personal wishes and settings

**Include the library:**

Use 'statisticFunctionalities\\functions\\Correlation';

**Adjust the options as wanted**

```
//example for setting the options
$options = [
    "FileToCheck"           => json_decode(file_get_contents("../generatedFiles/generatedInformation.json")),
    "KeyToSearchFor"        => "Operatieduur",
    "KeyToSelect"           => "Verrichting 1",
    "ValueForKeyToSelect"   => "Verwijderen buisjes uit oren",
    "ExcludeKeywords"       => ["Patiëntnummer", "Casusnummer"]
];

```

**Initialize the deviation class**

```
$correlation = new statisticFunctions\Correlation($options);

```

**Get the results**

```
$results = $correlation->calculateCorrelations();

```

What does my result contain?
----------------------------

[](#what-does-my-result-contain-1)

**xTitle** - Title of the x-axis that was being measured

**yTitle** - Title of the y-axis that was being measured

**coefficient** - the correlation coefficient between the values of xTitle and yTitle ### These results can be used to get a advise if wanted

[](#these-results-can-be-used-to-get-a-advise-if-wanted)

```

    //Result: The variable 'Operatieduur' looks like growing when 'Wond open (min)' is higher. The correlation is stated as moderate correlation: 0.51029910576627

```
