## How do you save model Sklearn?

Saving Machine Learning Modelsfrom sklearn.linear_model import LogisticRegression from sklearn import datasets import pickle from sklearn.externals import joblib.# Load the iris data iris = datasets. # Train a naive logistic regression model clf = LogisticRegression(random_state=0) clf. # Save the trained model as a pickle string.

**How do you save a model in Scikit?**

Save Your Model with pickle Pickle is the standard way of serializing objects in Python. You can use the pickle operation to serialize your machine learning algorithms and save the serialized format to a file. Later you can load this file to deserialize your model and use it to make new predictions.

### How do I save a Random Forest model in python?

Simply use python cpickle library for this:import cPickle.rf = RandomForestRegresor()rf.fit(X, y)with open(‘path/to/file’, ‘wb’) as f:cPickle.dump(rf, f)# in your prediction file.with open(‘path/to/file’, ‘rb’) as f:rf = cPickle.load(f)

**How do you import logistic regression?**

First, import the Logistic Regression module and create a Logistic Regression classifier object using LogisticRegression() function. Then, fit your model on the train set using fit() and perform prediction on the test set using predict().

## What is logistic regression with example?

Logistic Regression is one of the most commonly used Machine Learning algorithms that is used to model a binary variable that takes only 2 values â€“ 0 and 1. The objective of Logistic Regression is to develop a mathematical equation that can give us a score in the range of 0 to 1.

**How would you create a logistic regression model?**

In order to build a logistic regression model, we should have a target variable which is discrete. Hence let’s convert the particular column into a categorical column by thresholding it on a particular value.

### How is logistic regression done?

Logistic regression measures the relationship between the categorical dependent variable and one or more independent variables by estimating probabilities using a logistic function, which is the cumulative distribution function of logistic distribution.

**Where is logistic regression used?**

Like all regression analyses, the logistic regression is a predictive analysis. Logistic regression is used to describe data and to explain the relationship between one dependent binary variable and one or more nominal, ordinal, interval or ratio-level independent variables.

## When should logistic regression be used?

Use simple logistic regression when you have one nominal variable and one measurement variable, and you want to know whether variation in the measurement variable causes variation in the nominal variable.

**Why is logistic regression better?**

Logistic Regression uses a different method for estimating the parameters, which gives better resultsâ€“better meaning unbiased, with lower variances. Get beyond the frustration of learning odds ratios, logit link functions, and proportional odds assumptions on your own.

### What are the two main differences between logistic regression and linear regression?

The essential difference between these two is that Logistic regression is used when the dependent variable is binary in nature. In contrast, Linear regression is used when the dependent variable is continuous and nature of the regression line is linear.
