Abstract:
Unemployment is associated with depression in people living with HIV (PLWH). However, few studies have examined the effects of unemployment on PLWH with different levels of depression. The current study explores the plausible differential effects of unemployment on the different percentiles of depression in PLWH employing a quantile regression (QR) approach, based on a recent survey of 411 PLWH in China. Among participants, 47.7% had elevated depressive symptoms, and 23.8% were unemployed. The effects of unemployment on depression were statistically significant with a trend of initial increase followed by a decline at the quantile levels of 0.51-0.90 of depression. The maximum effect of unemployment status on depression was statistically significant at the 70th and 75th percentiles of depression (coefficient = 7.0, p < .01). Tailored strategies and interventions should be implemented to address the differential needs of PLWH with various levels of depressive symptoms.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
