Using RStudio to Estimate a Logistic Model

In this video, I demonstrate how to use RStudio to estimate and make predictions with a logistic model, using data imported from an Excel workbook. The explanation uses the following example: Thirty recent mortgage applications are obtained to analyze the mortgage approval rate. The response variable 𝑦 equals 1 if the mortgage loan is approved, 0 otherwise. It is believed that approval depends on the percentage of the down payment (𝑥_1) and the percentage of the income-to-loan ratio (𝑥_2). Estimate and interpret the logistic model. Predict the loan approval probability for an applicant with a 20% down payment and a 30% income-to-loan ratio. What if the down payment was 4%, 30%, 60%?
