Sp00kyVectors 0.1.12

A spooky vector analysis library

🎃 Sp00kyVectors: Vector Analysis wrapper for Python

Welcome to Sp00kyVectors, the eerily intuitive Python class for vector analysis, statistical computation, and visualizations 🪄👻

Whether you’re chasing spectral patterns or just need stats from dirty data, this library’s got your back (from beyond).

🧼 Examples

Before	After

🧹 Dirty Data? No Problem!

Load without worry

Easily load and align mismatched CSV files. This utility intelligently collects, normalizes, and organizes messy datasets — so you can focus on the analysis, not the cleanup. 🚀

Vector.load_folder(path) loads a folder of CSV files with potentially mismatched or missing columns,
aligns all columns based on their headers, and combines them into a single clean DataFrame.
Missing columns in any file are automatically filled with NaN values to maintain consistency.

Perfect for messy datasets where CSVs don't share the exact same structure!

Cleaning is done one layer up with sp00kyDF.get_clean_df() ✨🧹

This method returns a cleaned version of the DataFrame by performing the following steps:

1. 🧩 Removes duplicate rows (performed twice to ensure thorough cleaning)
2. 🚫📊 Clips outlier values based on the Z-score method (an Interquartile Range (IQR) method is also available)
3. 🏷️ Standardizes column names for consistency
4. ❌🕳️ (Optionally drops null values — currently commented out)

Finally, it returns the cleaned DataFrame ready for analysis. 🎯

🎛️⚙️✨ Granular Control? No Problem!

📚 Documentation

🧪 Class: Vector

✨ Initialization

Create a new Vector from a list or numpy array.

from sp00kyvectors import Vector

v = Vector([1, 2, 3, 4, 5])

If you're working with 2D data:

v2d = Vector([[1, 2], [3, 4], [5, 6]])

---

📊 Methods

.mean()

Returns the mean of the vector.

v.mean()  # ➜ 3.0

---

.median()

Returns the median.

v.median()  # ➜ 3

---

.std()

Returns the standard deviation.

v.std()  # ➜ 1.5811...

---

.normalize()

Normalizes the vector using Z-score (zero mean, unit variance).

v_norm = v.normalize()

---

.entropy(other: Vector)

Computes Shannon entropy between this vector and another.

v2 = Vector([1, 1, 1, 1, 6])
v.entropy(v2)  # ➜ ~0.72 (varies based on normalization)

---

.difference(other: Vector)

Returns a new Vector representing the difference between this vector and another.

v3 = v.difference(v2)

---

.project(dim: int)

Projects a 2D vector onto a specific dimension (0 = x, 1 = y).

vx = v2d.project(0)
vy = v2d.project(1)

---

🔢 Linear Algebra Methods

.magnitude()

Returns the magnitude (length) of the vector.

v.magnitude()  # ➜ 7.416

---

.angle(other: Vector)

Returns the angle between this vector and another, in radians.

v.angle(v2)  # ➜ 0.225 (radians)

---

.dot(other: Vector)

Computes the dot product of this vector and another.

v.dot(v2)  # ➜ 24

---

.cross(other: Vector)

Computes the cross product (only for 3D vectors).

v3d = Vector([1, 2, 3])
v3d2 = Vector([4, 5, 6])
v3d.cross(v3d2)  # ➜ [-3, 6, -3]

---

.projection(other: Vector)

Returns the projection of this vector onto another.

v.projection(v2)  # ➜ Vector with projected values

---

📈 Plotting

.histogram(log=False)

Plots a histogram of the vector values. Set log=True for logarithmic scale.

v.histogram()
v.histogram(log=True)

---

.plot_vectors(mode="line", entropy=False)

Plots 2D vectors.

• mode: "line", "arrow", or "trail"
• entropy: if True, colorizes vectors by entropy

v2d.plot_vectors(mode="arrow", entropy=True)

---

🔮 Utilities

.gaussian_smooth(sigma=1.0)

Applies Gaussian smoothing to the vector.

v_smooth = v.gaussian_smooth(sigma=2.0)

---

💀 Dunder Methods

__repr__()

Pretty string representation.

print(v)  # Vector(mean=3.0, std=1.58, ...)

---

🛠 Developer Notes

• Internal data is stored as numpy.ndarray
• Methods use scipy.stats, numpy, and matplotlib
• Entropy assumes aligned distributions (normalized first)
