您可以使用scikit-learn库中的SVM模型来对这15个变量进行预测，以下是示例代码：

from sklearn import svm
from sklearn.model_selection import train_test_split

# 将15个变量组合成一个特征矩阵X
X = np.hstack((X1_new, X2_new, X3_new, X4_new, X5_new, X6_new, X7_new, X8_new, X9_new, X10_new, X11_new, X12_new, X13_new, X14_new, X15_new))

# 划分训练集和测试集
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=0)

# 训练SVM模型
clf = svm.SVC()
clf.fit(X_train, y_train)

# 预测测试集结果
y_pred = clf.predict(X_test)

在上面的示例代码中，我们首先将15个变量组合成一个特征矩阵X。然后，我们使用`train_test_split`函数将数据集划分为训练集和测试集。接着，我们使用`SVC`函数创建了一个SVM模型，并使用`fit`方法对模型进行训练。最后，我们使用`predict`方法对测试集进行预测，并将结果保存在`y_pred`变量中。
