Frequently Asked Questions (FAQs)
What is a Home Points Spread?
A home points spread is a betting line set by bookmakers that reflects the expected difference in score between two teams playing at one team's home venue. Bettors can wager on whether the favorite will cover or underperform this line or if the underdog will outperform it by more than the specified margin.
How Do I Interpret a -7.5 Spread?
A -7.5 spread means that the favored team (playing at home) must win by more than 7.5 points for bets on them to pay out. If you bet against them (on the underdog), they would need to lose by less than 7.5 points or win outright for your bet to be successful.
Why Is Home Court Advantage Important?
Home court advantage refers to the benefit a team receives from playing in their own venue due to familiarity with the environment, support from local fans, and reduced travel fatigue. This can significantly impact performance and is often reflected in betting spreads.

*************
## Suggestions for complexity
1. **Weighted Nearest Neighbor**: Modify `_get_1NN_centroids_by_label` function so that it computes centroids using weighted distances rather than simple Euclidean distances.
2. **Parallel Processing**: Implement parallel processing using multiprocessing library or joblib library to speed up distance calculations especially when dealing with large datasets.
3. **Dynamic Distance Metrics**: Allow dynamic selection of different distance metrics (e.g., Manhattan distance, cosine similarity) based on user input.
4. **Handling Missing Values**: Enhance the function so that it can handle missing values (NaNs) gracefully within `X_df`.
5. **Incremental Updates**: Adapt the function so that it can handle incremental updates where new data points are added without recalculating everything from scratch.
## Conversation
<|user|>_hi i need help wth some code [SNIPPET]<|end|>
<|assistant|>_Sure! How can I assist you with this code? Do you need an explanation or some modifications?<|end|>
<|user|>_can we use diff distance metric instead cdist<|end|>
<|assistant|>_Certainly! We can modify `_get_1NN_centroids_by_label` function to accept a parameter specifying which distance metric to use. Here's how you can do it:
python
from scipy.spatial import distance
def _get_1NN_centroids_by_label(X_df, y, metric='euclidean'):
    X = X_df.values
    centroids = np.empty(X.shape)
    distances = distance.cdist(X,X, metric=metric)
    labels = np.unique(y)
    # init empty arrays
    label_indices = [np.array([], dtype=np.int) for l in labels]
    label_centroids = [np.empty(X.shape) for l in labels]
    # get indices by label
    for i,l in enumerate(y):
        label_indices[l].append(i)
    # get centroids by label
    for l,Li in enumerate(label_indices):
        d = distances[np.ix_(Li,Li)]
        for i,x_index in enumerate(Li):
            # get nearest point (not self)
            nearest_index = Li[np.argmin(d[i][np.arange(len(Li))!=i])]
            # get nearest point coordinates
            nearest_point = X_df.values[int(nearest_index)]
            # put nearest point coordinates at current index
            label_centroids[l][x_index] = nearest_point
            
    return pd.DataFrame(centroids)
# Example usage:
# _get_1NN_centroids_by_label(X_df=my_data_frame, y=my_labels_array, metric='cityblock')
This code now allows you to specify different metrics like 'cityblock' (Manhattan distance), 'cosine', etc.<|end|>
<|user|>_great but what if data has NaNs<|end|>
<|assistant|>_Good question! We need to handle NaNs carefully since they can disrupt distance calculations.
One way is to impute missing values before calculating distances. Another way is to modify our calculation logic so it skips NaNs.
Here's an approach where we skip NaNs during distance calculation:
python
from scipy.spatial import distance
def _nan_euclidean(u,v):
    """Custom Euclidean distance ignoring NaNs"""
    mask = ~np.isnan(u) & ~np.isnan(v)
    return np.sqrt(np.nansum((u[mask] - v[mask])**2))
def _get_1NN_centroids_by_label(X_df, y):
    X = X_df.values
    
    def custom_distance_matrix(a,b):
        dist_matrix = np.zeros((a.shape[0], b.shape[0]))
        for i in range(a.shape[0]):
            for j in range(b.shape[0]):
                dist_matrix[i,j] = _nan_euclidean(a[i], b[j])
        return dist_matrix
    
    distances = custom_distance_matrix(X,X)
    labels = np.unique(y)
    # init empty arrays
    label_indices = [np.array([], dtype=np.int) for l in labels]
    label_centroids = [np.empty(X.shape) for l in labels]
    # get indices by label
    for i,l in enumerate(y):
        label_indices[l].append(i)
    # get centroids by label
    for l,Li in enumerate(label_indices):
        d = distances[np.ix_(Li,Li)]
        for i,x_index in enumerate(Li):
            # get nearest point (not self)
            nearest_index = Li[np.argmin(d[i][np.arange(len(Li))!=i])]
            # get nearest point coordinates 
            nearest_point = X_df.values[int(nearest_index)]
            # put nearest point coordinates at current index 
            label_centroids[l][x_index] = nearest_point
            
    return pd.DataFrame(centroids)
# Example usage:
# _get_1NN_centroids_by_label(X_df=my_data_frame_with_nans, y=my_labels_array)
This modification includes a custom `_nan_euclidean` function that calculates Euclidean distance while ignoring NaNs.
