Assumptions about explanatory variables and errors are central in regression analysis. For example, the well-known method of ordinary least squares yields consistent and efficient estimators if the underlying error terms are independently, identically, and normally distributed. Additionally, the...

The body mass index (BMI) reflects current net nutrition and health during economic development. This study introduces a difference-in-decompositions approach to show that although 19th century African-American current net nutrition was comparable to working class whites, it was made worse-off...

Using a new source of 19th century state prison records, this study contrasts the biological living conditions of comparable US African-American and white female statures during economic development. Black and white female statures varied regionally, and white Southeastern and black Southwestern...

Using data from late 19th and early 20th century US prisons, this study estimates the basal metabolic rates and calories for Americans of European descent. Throughout the 19th century, white basal metabolic rates (BMRs) and calories declined across their respective distributions, and much of the...

Average stature reflects cumulative net nutrition and health during economic development. This study introduces a difference-in-decompositions approach to show that although 19th century African-American cumulative net nutrition was comparable to working class whites, it was made worse-off with...

When traditional measures for economic welfare are scarce or unreliable, stature and the body mass index (BMI) are now widely-accepted measures that reflect economic conditions. However, little work exists for late 19th and early 20th century women's BMIs in the US and how they varied with...

Heights and body mass index values (BMIs) are now well accepted measures that reflect net nutrition during economic development and institutional change. This study uses 19th century weights instead of BMIs to measure factors associated with current net nutrition. Across the weight distribution...

Little research exists on the body mass index values of 19th century Americans of European descent. Using a new BMI data set and robust statistics, between 1860 and 1880, BMIs decreased across the distribution; however, after 1880, BMIs in the highest quantiles increased, while those in lower...

Using a source of 19th century U.S. state prison records, this study addresses European-American stature variation. The most commonly cited sources for stature variation are diets, disease, and work effort. However, vitamin D is also vital in human statures and health. This paper demonstrates...

By using a new source of 19th century Texas state prison records, the present study contrasts the biological living conditions of comparable blacks and whites in the American South between the Civil War and Reconstruction. White stature exceeded black stature. Between 1850 and 1870, black...
