Dear all,

A dataset with 11 variables was imported to STATA using File -> Import Excel spreadsheet. Then, Data -> Create or change data -> Convert variables from string to numeric was used.

Stata recognised two types of numeric variables: byte for dummy and double for other. Function "describe" identifies 184 observations, but a regression that I run provides me with only 142 observations.

Dataex reveals that some values were replaced into dots instead of numbers, however in the original excel file all values seem to be fine. It contains numerical values and there should not be any issues.

Could you please help me fix this problem?
I'm looking forward to any ideas on how it can be fixed
